  • Kink Waves in an Extended Nonlinear Schrödinger Equation with
           Allowance for Stimulated Scattering and Nonlinear Dispersion
    • Abstract: We study the stationary wave solutions of an extended nonlinear Schrödinger equation with nonlinear dispersion and stimulated scattering. New classes of the kink waves with nonlinear phase modulation, the existence of which is stipulated by the balance of nonlinear dispersion and stimulated scattering, have been found.

  • Features of the Shock-Wave Generation In High-Intensity Bounded Acoustic
           Beams in the Presence of a Soft Boundary in the Interaction Region
    • Abstract: This paper is devoted to experimental studies of interaction between intense acoustic fields and their interfaces. In particular, we discuss the results of experimental studies of the spatial variation of the profile and spectrum evolution of an intense acoustic wave reflected from an acoustically soft boundary. The distance between the source aperture and the surface approximately corresponds to the coordinate of the last diffraction maximum in the axial distribution of the acoustic field at the pump frequency. The radiation intensity was chosen in such a way as to ensure the nonlinear wave interaction both before and after the reflection. It is shown that antiphased interaction between harmonics in the reflected wave formed before the boundary and the harmonics formed after the refection leads to a significant variation in the profile and spectrum of the reflected wave, which determines the further formation of nonlinear waves. Propagation of the reflected wave is accompanied by an intense rise in signal amplitude in the compression phase and the formation of a new shock-wave front. A nonmonotonic decay as a function of the harmonic number is observed in the harmonic amplitude distribution. This feature of the spectrum behavior takes place in the increasingly low-frequency part of the spectrum as the distance from the boundary increases.

  • On the Doppler Frequency Shifts of Radar Signals Backscattered from the
           Sea Surface
    • Abstract: We study the frequency spectra of the radar signals scattered from the wind waves on the sea surface in the full-scale experiment. Two types of the radar Doppler shifts of the spectrum maximum, namely, the averaged shift of the instantaneous spectrum of the scattered signal and the shift of the maximum of the signal time-averaged spectrum as functions of the incidence angle and the wind velocity and direction are analyzed for different sounding-wave polarizations. Significant difference between the average shift of the instantaneous spectrum and the shift of the average-spectrum maximum is demonstrated. This difference is attributed to the radar-signal modulation effect in the field of long surface waves. The obtained results are very important for correct retrieval of the velocities of the surface currents using the data of the satellite-borne measurements of the radar Doppler shifts.

  • Quasi-Standing Wave Dragging Effect in a Rotating Ring Laser in the
           Presence of an Optical Medium
    • Abstract: We consider quasistanding waves in a rotating ring laser, whose nodes and antinodes are immobile with respect to the inertial reference frame in the absence of an optical medium in the resonator. In this case, the nodes and antinodes of the quasistanding waves rotate with the laser rotation velocity with respect to the reference frame which rotates along with the ring laser. It is shown that the quasistanding-wave motion in the rotating reference frame slows down a factor of n2 if an optical medium with the refractive index n is present in the ring laser. In this case, the waves move with respect to the inertial reference frame with a velocity that is proportional to the Fresnel dragging coefficient 1 – 1/n2.

  • Principles of Designing an “Ideal” System of Imaging Through a
           Rough Water Surface
    • Abstract: We propose new principles for designing a system of imaging through a rough water surface. These principles permit one to reduce the negative impact of the surface roughness and multiple scattering in water on the spatial resolution. The system model in which the image of underwater objects is generated by angular scanning with an illumination beam is considered. Image distortions in such a system are due mainly to random variations in the refraction angle of a laser beam on the surface and can be eliminated if the true direction of entry of the beam into water is known. Information on the beam refraction angle is suggested to be taken from the angular distribution of the radiance of the signal backscattered by the subsurface water layer. Reduced impact of multiple scattering in water is reached by high-frequency modulation of the beam power by a complex signal and matched processing in the reception system. It is shown that a combination of proposed imaging techniques gives an essential gain in the resolution of the airborne imaging system.

  • The Possibility of Increasing the Throughput of a High-Frequency
           Radio-Communication Channel Using a Mimo System
    • Abstract: We consider the possibility of increasing the radio-channel throughput in the high-frequency range by using antenna arrays. The MIMO-system efficiency is studied with the help of the modified Watterson model by the simulation method. The signal parameters for which the MIMO processing yields the best results are determined.

  • Quasioptimal Estimation of Motion Parameters Based on Laser Ranging
    • Abstract: An algorithm for estimation of range, velocity, and acceleration based on measurements of range in each repetition period of the probing sequence of optical pulses is synthesized. Characteristics of estimates with allowance for abnormal errors are found. It is shown that the proposed estimates are consistent, asymptotic (the signal-to-noise ratio increases for each pulse), unbiased, and effective.

  • On Using Cyclotron Waves for Output of Radiation from High-Power
           Relativistic Backward-Wave Oscillators
    • Abstract: We discuss the scheme of a high-power relativistic backward-wave oscillator operating with a high-current explosive-emission electron beam. The radiation output from the tube is based on reflection of the operating wave into a fast cyclotron wave which transmits the energy of the high-frequency field towards the collector. At the collector, reverse conversion into the output electromagnetic wave takes place. The proposed scheme allows one to increase electric strength, as well as the transverse size of the working space of the backward-wave oscillator. It is shown that within the proposed scheme, one can reduce the focusing magnetic field without decreasing the power of the output radiation.

  • Bandpass Filters Based on L-ridged Rectangular Waveguides
    • Abstract: We solve the problem of electrodynamic analysis and synthesis of bandpass filters based on rectangular waveguides with complex L-shaped ridges. Cutoff wave numbers and components of the electromagnetic field were calculated by the partial region method with allowance for the singularity of the electromagnetic field on metal ribs. As a prototype, the model of a cutoff filter and an approximation of its amplitude-frequency characteristic by the Chebyshev polynomials were used. Examples of synthesis of narrow-band filters with inputs based on a rectangular waveguide and an H-waveguide are presented. Advantages of using a novel waveguide with a complex cross section in the filter are considered, including the appearance of a total reflection frequency (antiresonance) in the filter rejection band, which allows one to significantly extend this band and increase the attenuation level in it.

  • Scattering of an Electromagnetic Wave by a Structure Consisting of Several
           Thin Dielectric Cylinders with Finite Lengths
    • Abstract: We generalize a version of the auxiliary-source method, which was proposed earlier to solve the problem of scattering of an electromagnetic field by a single thin dielectric cylinder, to the case of a structure consisting of several noncrossing cylinders of such a type. The specially developed computer code is briefly described. The results of numerical calculations of the scattering cross sections for some particular structures are reported.

  • Impact of the Elf Receiver on Characteristics of the Observed Q-bursts
    • Abstract: We consider the impact of a typical Schumann-resonance receiver on the waveforms of the ELF transients, or Q-bursts. For this purpose, the Q-bursts were calculated both in the frequency and the time domains. The data obtained within the framework of the frequently used models of the propagation constant are compared. The effect of a typical ELF receiver containing a 4–40-Hz bandpass filter combined with a 50-Hz notch filter is evaluated. The main attention is given to distortions in the pulsed signal waveform. It is found to what extent a Schumann-resonance receiver retards the pulse, how the ratio between the amplitudes of the positive and negative half-waves at the pulse front is modified, and how the antipodal and round-the-world subpulses are distorted. Since such distortions are able to impede correct identification of the ELF pulses and determination of the source polarity and the source-to-observer distance, we discuss the possible ways of compensating for the deformations produced by the receiver.

  • Small-Scale Turbulence of the Earth’s Magnetosheath
    • Abstract: We present the results of experiments on reception of the Sura facility signals in the 9-MHz range using the WIND spacecraft. The technique of determining the temporal spectrum of the Earth’s magnetosheath plasma irregularities with less than 100-km scales based on the radio scintillation spectrum in terms of the weak scattering theory is proposed and implemented. Using the in situ measurements of the electron number density onboard spacecraft with a temporal resolution of about 3 s, it has been found that the inner scale of the magnetosheath turbulence varies within 10–90 km with a mean value of about 30 km.

  • Analysis of the Throughput of the Cellular Radio-Communication Systems
           Using Coordinated Data Transmission to Suppress Mutual Unintended
           Interference
    • Abstract: We present the results of the comparative analysis of two data-transmission schemes of the fourth-generation cellular communication standard LTE-A, which use the “quasistatic” and “dynamic” coordination at the neighbor base stations. Both schemes are used to suppress mutual unintended co-channel interference resulting from the repeated use of one frequency channel by the neighbor base stations. The general case of the heterogeneous cellular radio-communication system with different station types (macro- and picostations) is considered. In this work, the efficiency of the coordinated-transmission schemes is studied along with the adaptive algorithms for the dataflow planning and control. The use of both coordination schemes is comparatively analyzed. An original algorithm for redistribution of the user connections is proposed for the dynamic scheme and the dependence of the communication-system throughput on the radio-network configuration and the number of base stations, that participate in the coordination is studied.

  • Recent Trends in Multimodal Optical Coherence Tomography. II. The
           Correlation-Stability Approach in OCT Elastography and Methods for
           Visualization of Microcirculation
    • Abstract: The second part of this paper continues the discussion of possibilities for combining functionally different types of biomedical characterization of tissues using optical coherence tomography (OCT). In the first part, polarization-sensitive imaging and conventional approaches to elastographic mapping in OCT were considered. Here, we consider an unconventional approach to elastographic mapping based on the analysis of variability of OCT images of the deformed tissue, omitting the stage of the displacement-field reconstruction. We also discuss methods for quantification of blood flow and visualization of microvasculature, some of which have much in common with the elastographic approach based on the analysis of temporal variability of OCT frames. This similarity looks especially promising in the context of combining multiple contrast mechanisms to enable prospective multimodal OCT scanners, as is essential for biomedical progress given the complex and heterogeneous nature of real biological tissues.

  • Multi-Point Detection of the Elf Transient Caused by the Gamma Flare of
           December 27, 2004
    • Abstract: We present the experimental records of the radio pulse related to the gamma burst that took place on December 27, 2004. The records, which are synchronized by GPS time marks, were obtained in the observatories at Moshiri and Onagawa (Japan), Esrange (Sweden), Karimshino (Kamchatka, Russia), Nagycenk (Hungary), and Hornsund (Polish Polar Station Spitzbergen). The data demonstrate exceptional similarity and contain characteristic pulses that correspond to the time of gamma-ray arrival. Processing of the signals shows that along with the time match, the following modeling predictions are confirmed: radio pulses contain a signal at the main frequency of the Schumann resonance, the field source has positive polarity (the current is directed from the ionosphere towards the Earth), the polarization of the horizontal magnetic field of the radio wave is almost linear, and the directions towards the source indicate the epicenter of the gamma-quanta flux collision with the ionosphere. These properties correspond to the concept of the parametric electromagnetic pulse that is produced due to a significant change in the current in the global electric circuit, which is caused by a cosmic gamma-ray flare.

  • Aperiodic Large-Scale Disturbances in the Lower Ionosphere. Ionosonde
           Observation Results
    • Abstract: We present the observed disturbances of the parameters of the ionosphere affected by high-power radio waves from the SURA heating facility. Ionosondes located in Nizhny Novgorod and Moscow (Russia), Kharkov (Ukraine), and Pruhonice (Czechia) were used for the observations. The diagnostic tools were from 560 to 2200 km away from SURA. Additional ionization layers with a cutoff frequency of 2.6–3.4 MHz were occasionally observed on the ionograms of the Nizhny Novgorod and Moscow stations. The effective altitude of these layers was 120–160 km and the true altitude was about 110–130 km. The occurrence of additional ionization layers below 100–130 km was controlled by an increase in the minimum observable frequency (MOF). For the Moscow station, the MOF increased by about 1 MHz in the daytime and almost did not change in the night time. MOF variations on the ionograms of the Kharkov and Pruhonice stations were less significant (0.3–0.4 MHz) in all time of the day. The observed effects are most probably due to the midlatitude precipitation of electrons from the inner radiation belt, which increased the electron number density in the ionosphere, absorption of the sounding radio waves, and the MOF. Estimated particle flux density was 108–109 m−2 ·s−1. The electron number density in the daytime increased by a factor of 2–3.

  • Corrugation Profile for the Quasioptical Polarization Separator
    • Abstract: We consider and classify the regime of separation of two orthogonally polarized E and H waves by using a reflecting metal diffraction grating, which sends all the energy of an incident wave with one polarization to the specular order of diffraction, and that of an incident wave with the other polarization, to the (−1)st order of diffraction (in this case, the autocollimation regime is used). The conditions of existence of such a regime are studied in the simplest cases (generalization of the approach presented in [1, 2] to the case of a sinusoidal surface), along with the possibility to construct more complex (nonsinusoidal) corrugation profiles, for which the specified regime has certain advantages, e.g., a wider bandwidth. Examples of such profiles are presented. The studies are performed on the basis of numerical solution of the problem of diffraction of a plane electromagnetic wave by a perfectly conducting corrugated surface within the framework of the integral-equation method employing the authors’ computer visualization code.

  • Filtering Features of Long Acoustic-Gravity Waves in a Windless Atmosphere
    • Abstract: Equations for the wave perturbations of velocity and pressure in a nonisothermal atmosphere are considered. It is noted that the pressure perturbation has singularities near the altitude where the equality of the horizontal phase velocity of the perturbation and sound velocity in the medium is fulfilled. At this altitude, a thin atmospheric layer with finite mass is concentrated. The wave perturbations do not penetrate to a higher level. The presence of a singularity in the wave perturbation of pressure was numerically confirmed for the actual altitude temperature profiles of the atmosphere.

  • Aperture Synthesis due to the Motion of a Single Receiver During Direction
           Finding of the Narrowband Noise Sources
    • Abstract: We consider the possibilities of the aperture synthesis using a single moving receiver during direction finding of the sources emitting a random stationary narrowband signal. It is shown that in this case the coordinates and projections of the source velocities can be determined from the current estimates of the Doppler frequency shift. Using the Cramér–Rao bound, we analyze accuracy of determining the parameters which characterize the rectilinear trajectory of the source during the circumferential receiver motion as functions of the synthetic-aperture size, emittedsignal bandwidth, signal-to-noise ratio, etc. Possible applications of the proposed version of the aperture synthesis in underwater acoustics and radio astronomy are considered.
