  • Analysis of a right isosceles triangular waveguide fed longitudinal slot
           antenna
    • Authors: S.S. Kakatkar;A.A Deshmukh;K.P. Ray;
      Pages: 641 - 643
      Abstract: A right isosceles triangular waveguide fed longitudinal slot has been analysed in this Letter by employing the method of moments. The internal admittance has been evaluated by using the image technique to simplify the problem from that of a slot in a triangular waveguide wall to that of two slots in a square waveguide, one each in an adjacent wall. A triangular waveguide has been fabricated and measurements have been taken on slots cut in one of the two equal sides of the triangular waveguide. It has been shown that the theoretical results agree well with the measured results. The theory is useful in the design of triangular waveguide fed slot arrays.

  • Bandwidth-enhanced four-antenna MIMO system based on SIW cavity
    • Authors: Bing-Jian Niu;Yan-Jie Cao;
      Pages: 643 - 645
      Abstract: A bandwidth-enhanced four-antenna multiple-input–multiple-output (MIMO) system based on a substrate-integrated-waveguide (SIW) cavity is proposed. By etching two long rectangular slots on the top plane of the cavity, four quarter-mode sub-cavities with the same size are constructed and then individually fed by a coaxial port to form a four-antenna MIMO system. Suitable port isolation is achieved by optimising the length and width of these slots. To enhance bandwidth, a pair of back-to-back L-shaped slots is cut to split each sub-cavity into three smaller parts. Three resonant modes are generated in these parts and merged into the operating band. A sample with the overall size of 0.58λ0 × 0.58λ0 × 0.02λ0 has been fabricated. Measured bandwidth is enhanced from 80 to 230 MHz and measured isolation is better than 15.0 dB. Owing to covering the band of 3.40–3.60 GHz, the proposed antenna system has potential applications for fifth-generation communication.

  • Periodic strip loaded reconfigurable half-mode substrate integrated
           waveguide-based leaky wave antennas
    • Authors: M. Singh;B. Ghosh;
      Pages: 646 - 648
      Abstract: In this Letter, a reconfigurable half-mode substrate integrated waveguide (HMSIW)-based leaky-wave antenna (LWA) configuration with its edge loaded with the periodic strips is investigated. A good impedance matching is obtained using the loaded configuration. A microstrip line with a tapered-line transition is used to feed the proposed antenna structure. Beam scanning of 24°–66° in the frequency band 9.07–11.04 GHz is achieved with the maximum gain of 14.58 dBi at the frequency 10.07 GHz with a corresponding beam direction of 48°. Thereafter, the edge of the strips is loaded in the middle with variable capacitors connected through narrow stubs to scan the beam at a fixed frequency. The variation in reflection and transmission coefficients, beam angle and antenna gain with variation in the capacitor value for the loaded configuration is investigated.

  • Dual-energy approach to reduce cone-beam artefacts in a circular orbit
           cone-beam CT system
    • Authors: C. Han;J. Baek;
      Pages: 648 - 650
      Abstract: The authors propose a dual-energy approach to reduce cone-beam artefacts in a circular orbit cone-beam computed tomography (CT) system. When there exist multiple dense structures within a large cone angle, two-pass algorithm is ineffective for reducing cone-beam artefacts because high-density materials are incorrectly segmented with simple thresholding. The proposed algorithm utilises projection data obtained with dual-energy X-ray spectra to estimate projections of the high-density materials from multi-density anatomical structures. Using bone and water as two of basis functions, the projection data of bone materials can be precisely estimated via dual-energy scans. Then, bone-only images are reconstructed by a constrained total-variation minimisation-based iterative algorithm. The reconstructed bone images are used to generate cone-beam artefacts and the final corrected images are acquired by subtracting the generated cone-beam artefacts from the original Feldkamp, Davis, and Kress images. The proposed method was validated using an extended cardiac-torso phantom with complex vertebral anatomy and compared with the two-pass algorithm. The results show that the proposed method restores distorted bony structures and intensity values, especially in regions with large cone angles. A qualitative evaluation of the mean-squared errors and structural similarities demonstrates the effectiveness of the proposed method compared to the two-pass algorithm.

  • Extraction of respiratory rate from PPG using ensemble empirical mode
           decomposition with Kalman filter
    • Authors: H. Sharma;
      Pages: 650 - 653
      Abstract: This Letter suggests a simple but effective approach for accurate estimation of respiratory rate (RR) from the photoplethysmogram (PPG). In the suggested technique, the PPG signal is first decomposed into a number of intrinsic mode functions (IMFs) using the ensemble empirical mode decomposition (EEMD). The IMFs comprising respiratory information are selected and used to reconstruct the signal. A Kalman filter coupled with the signal quality measure of PPG is utilised to process the reconstructed signal to derive the respiratory signal for RR estimation. Experiments are conducted on two independent datasets, namely CapnoBase and MIMIC. Based on experimental results, the technique is found to be outperforming the existing methods by achieving lower error in the estimated RRs on both datasets. This work demonstrates the potential of the EEMD method with Kalman filter for precise estimation of RR from PPG to contribute to the advancement of portable healthcare systems with a fewer number of sensors.

  • A High-linearity Input-Buffer with high output common-mode stability for
           10bit 3.2GSs ADC
    • Authors: Ting Sun;Jing Li;Ning Ning;Kejun Wu;Qi Yu;
      Pages: 653 - 655
      Abstract: A high-linearity input-buffer with high output common-mode stability for 10-bit 3.2 GS/s ADC is proposed in this Letter. The buffer is mainly composed of a source follower for strong driving ability. To enhance its linearity, a feed forward signal path from input to output is proposed. A replica buffer-based common-mode feedback is designed to achieve high output common-mode stabilisation of input-buffer. The prototype is implemented in 40 nm CMOS process. The output common-mode variation is reduced from 200 to 1 mV. Input-buffer consumes 96 mW in 3.2 GHz sampling rate and achieves 69.3 dB spur-free dynamic range at 1581 MHz input frequency.

  • Model predictive control with a novel cost function evaluation scheme for
           OW-PMSM drives
    • Authors: Zhihao Zheng;Dan Sun;Mingze Wang;Heng Nian;
      Pages: 655 - 657
      Abstract: In open-winding permanent magnet synchronous motor (OW-PMSM) system, the voltage vectors (VVs) produced by the dual-inverter are abundant and one VV may correspond to different switching states. It is time-consuming for model predictive control strategy to evaluate the cost function with all VVs and select the optimal switching states. A novel cost function evaluation scheme is proposed in this Letter and the evaluation times of the cost function is significantly reduced. The optimal switching states of each phase are decided by evaluating the cost function with six virtual vectors and a zero vector and the switching states of each phase are directly decided without additional evaluation process. The calculation time is significantly reduced with the proposed strategy and the steady-state performance of the OW-PMSM system is maintained similar to the conventional strategy. Experimental results have validated the effectiveness of the proposed strategy.

  • Probabilistic analysis of field coupling to transmission lines using
           hybrid method
    • Authors: H. Gheddar;M. Melit;B. Nekhoul;
      Pages: 657 - 659
      Abstract: The main purpose of this work is to give a global analysis of external field coupled to multiconductor transmission line (MTL). Knowing that this problem is largely treated using determinist approach and the results strongly depend both on the configuration of MTL and external field parameters, for this reason, the authors proceed by a hybrid method which combines a probabilistic approach (polynomial chaos) and the equivalent cable bundle method. The field's parameters and the length of MTL are both considered as random variables.

  • Enhanced global attention upsample decoder based on enhanced spatial
           attention and feature aggregation module for semantic segmentation
    • Authors: Lianglu Yin;Haifeng Hu;
      Pages: 659 - 661
      Abstract: This work designs a simple but effective decoder structure called Enhanced Global Attention Upsample Decoder (EGAUD) based on enhanced spatial attention (SA) and feature aggregation module for semantic segmentation, which is used to recover the prediction rich in detail and semantic information. First, Enhanced SA (ESA) and Feature Aggregation Module (FAM) are used to enhance the details and semantic information of shallow and deep features, respectively. ESA integrates the SA module and residual enhancement module to enrich spatial information while ensuring the effectiveness of backpropagation. FAM uses three parallel pooling operations to expand the receptive field of features, to optimize the semantic information. Then, the authors use Global Attention Upsample (GAU) to recover the feature resolution. From bottom to top, GAU utilises two pooling operations to fully integrate the features of adjacent layers. The results on two datasets, PASCAL VOC 2012 and PASCAL-Person-Part, show the effectiveness of the authors’ model.

  • Optical flow estimation combining with objects edge features
    • Authors: Bin Liao;Jinlong Hu;Tenghui Li;
      Pages: 661 - 663
      Abstract: Optical flow estimation has been concerned with biological plausibility since the optical flow was drawn from psychology. In this Letter, optical flow estimation combining with objects edge features is proposed. Inspired of functional division and collaboration of edge detection in primary visual cortex and motion information acquisition in a motion-selective area in the human visual cortex, a neural sub-network is introduced to extract motion edge information as primary visual cortex does, and the other neural sub-network is utilised to perceive motion information as a motion-selective area in visual cortex does. The inference sub-network in the authors’ model used augmentation features composed of objects, edge features and general features as inputs to predict the optical flow. In experiments on large displacements benchmark datasets, their approach showed promising results to improve the performance of optical flow comparing with the other models based on the visuomotor perception of visual cortex processing mechanism.

  • 260-GHz waveguide module containing an integrated InP HBT amplifier chip
    • Authors: C. Yi;J. Cho;J. Shin;M. Kim;
      Pages: 665 - 667
      Abstract: A terahertz integrated amplifier circuit packaged inside a WR-3.4 waveguide is presented. The circuit, fabricated using 250-nm InP technology, contains three amplifier chains each connected to its own input and output waveguide transition pairs. The size of the transition is minimised for the chip to properly fit inside the standard waveguide. The assembled waveguide module shows the peak amplifier gain of 13 dB and 3-dB bandwidth of 32 GHz as its gain is 6.2 dB less than that of an on-wafer amplifier measured using RF probes. The maximum measured output power from the module is 6.5 dBm at 260 GHz compared to 1.4 dBm from single on-wafer amplifier chain.

  • Compact dual-band balanced SIW bandpass filter with two adjustable
           closed-passbands
    • Authors: Yijie Liu;Gang Zhang;Jian Zheng;
      Pages: 667 - 669
      Abstract: A new compact multilayer dual-band-balanced bandpass filter (BPF) with two flexibly adjustable closed-passbands based on substrate-integrated waveguide (SIW) resonator is proposed in this letter. Both TE102-mode and TE201-mode of the resonator are utilised to achieve desired differential mode (DM) transmission and high common mode suppression. Two SIW cavities are properly coupled in the back-to-back form to realise a closed dual-passband-balanced response by virtue of singly one cruciform coupling aperture etched on the ground. Additionally, two pairs of perturbed slotlines are elaborately introduced on the top and bottom layers to perturb the resonant frequencies of TE102-mode and TE201-mode, realising both adjustable upper- and lower-DM passbands. For demonstration, a prototype dual-band-balanced SIW BPF operating at 12.7 and 15.5 GHz is designed, fabricated and tested. Measured and simulated results are in good agreement, verifying the feasibility of the design concept.

  • Vertical nanowire III–V MOSFETs with improved high-frequency gain
    • Authors: O.-P. Kilpi;M. Hellenbrand;J. Svensson;E. Lind;L.-E. Wernersson;
      Pages: 669 - 671
      Abstract: High-frequency performance of vertical InAs/InGaAs heterostructure nanowire MOSFETs on Si is demonstrated for the first time for a gate-last configuration. The device architecture allows highly asymmetric capacitances, which increases the power gain. A device with Lg = 120 nm demonstrates fT = 120 GHz, fmax = 130 GHz and maximum stable gain (MSG) = 14.4 dB at 20 GHz. These metrics demonstrate the state-of-the-art performance of vertical nanowire MOSFETs.

  • Measurement of Brillouin gain spectrum with dual-frequency laser for
           optical fibre sensor
    • Authors: M. Salhi;V. Kemlin;S. Faci;G. Baili;A. Khadour;S. Mostarshedi;A.-L. Billabert;
      Pages: 672 - 674
      Abstract: In this Letter, the authors present a first measurement of Brillouin gain spectrum with dual-frequency solid-state laser. This allows a coherent detection of the Brillouin backscattered spectrum in a frequency range below the hundreds of MHz by fine-tuning of the difference between the two cross-polarised fields emitted by the laser. The photodetection at low-frequency benefits from the balanced detection technique where high dynamic range measurements are largely available. The narrow line-width of the cross-polarised field permits also the direct measurement of the Brillouin spectrum line-width. The system is demonstrated by measuring the Brillouin frequency shift with temperature when standard single-mode fibre-28 (SMF-28) and large effective area fibre (LEAF) are fully heated. This gives temperature coefficients close to theoretical expectations with values of 1.16 MHz/°C for SMF-28 and 1.15 MHz/°C for LEAF.

  • Predictive function control in tertiary level for power flow management of
           DC microgrid clusters
    • Authors: Sucheng Liu;Rui Liu;Jiazhu Zheng;Xiaodong Liu;
      Pages: 675 - 676
      Abstract: Tertiary control is the highest level in hierarchical control of microgrids to perform power exchange between the microgrid and external networks. In this Letter, a tertiary control strategy based on predictive function control (PFC) is proposed to manage power flow in DC microgrid (DCMG) clusters. Unlike linear PI control suitable for single-input and single-output systems, the PFC strategy is a nonlinear control method and capable of multiple input and multiple output control tasks with multiple objectives optimisation on-line. By solving the cost function in the finite receding horizon, voltage set points are computed in real-time to create bus voltage difference for power transfer between interconnected DCMGs. The PFC-based tertiary control for the DCMG cluster is verified through simulations.

  • Iterative maximum likelihood estimation of the compound inverse Gaussian
           clutter parameters
    • Authors: K. Belhi;F. Soltani;A. Mezache;
      Pages: 677 - 678
      Abstract: This Letter aims at proposing a cost-effective method for estimating the parameters of the compound inverse Gaussian distributed clutter. Under the assumption of the absence of thermal noise, an iterative maximum likelihood estimator (IMLE) is proposed and compared with existing MLE, the [zlog(z)] estimator, the non-integer order moments estimator and the higher order moment estimator. The results obtained show that the IMLE method outperforms all the other methods and has similar estimation performance than the MLE method but requires lower computational time.

  • High-speed graded-channel AlGaN/GaN HEMTs with power added efficiency>70%
           at 30 GHz
    • Authors: J.S. Moon;R. Grabar;J. Wong;M. Antcliffe;P. Chen;E. Arkun;I. Khalaf;A. Corrion;J. Chappell;N. Venkatesan;P. Fay;
      Pages: 678 - 680
      Abstract: The authors report on highly scaled 60 nm gate length graded-channel AlGaN/GaN high electron mobility transistors (HEMTs) with a record power added efficiency (PAE) of 75% at 2.1 W/mm power density at Vdd = 10 V and the PAE of 65% at 3.0 W/mm power density at 30 GHz at Vdd = 14 V. Under two-tone power measurement, the graded-channel AlGaN/GaN HEMTs demonstrated similar power performance with peak PAE>70% at 30 GHz. This novel channel design shows great promise for high-efficiency millimetre-wave (mmW) power amplifiers up to 3 W/mm RF power density operation.

  • Improved LDMOS-SCR for high-voltage electrostatic discharge (ESD)
           protection applications
    • Authors: Wenqiang Song;Fei Hou;Feibo Du;Jizhi Liu;Zhiwei Liu;Juin J. Liou;
      Pages: 680 - 682
      Abstract: An improved lateral double-diffused MOS silicon-controlled rectifier (ILDMOS-SCR) for high-voltage electrostatic discharge (ESD) protection applications has been proposed and verified in a 0.18 µm 5 V/24 V BCD process. The proposed improved lateral double-diffused MOS silicon-controlled rectifier (LDMOS-SCR) is constructed by adding a gated P-type/intrinsic/N-type (PIN) diode into a conventional LDMOS-SCR. With part of the ESD current discharges from the surface gated PIN diode path, the proposed ILDMOS-SCR achieves a high holding voltage of 30 V as well as a high failure current of 10.04 A, which is evaluated to pass 15 KV Human Body Model (HBM) ESD stress.

  • AF relay assisted multiuser MIMO-DQSM downlink transmission system
    • Authors: F.R. Castillo-Soria;
      Pages: 682 - 684
      Abstract: This Letter presents an amplify and forward (AF) relay assisted multiuser multiple input-multiple output (MU-MIMO) downlink transmission system based on a double quadrature spatial modulation (DQSM) scheme. The authors analyse and compared the bit error rate performance of the proposed AF-MU-MIMO-DQSM system with its conventional counterpart AF-MU-MIMO system, which uses quadrature amplitude modulation/phase shift-keying modulation. Results show that the utilised technique can effectively cancel the interference produced by multiple users and multiple relays in the system. The proposed AF-MU-MIMO-DQSM system has up to 2 dB gain compared with the conventional system for the analysed cases.
