  • Study of the Plasma Turbulence Dynamics by Measurements of Diagnostic
           Stimulated Electromagnetic Emission. I. Experimental Results
    • Abstract: We consider the possibilities of studying the evolution of the plasma wave spectrum and artificial striations of the plasma density at different altitudes of the disturbed ionospheric region modified by high-power HF radio waves from the SURA heating facility based on measurements of the dynamic characteristics of diagnostic stimulated electromagnetic emission.

  • 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.

  • Phenomena in the High-Latitude Ionospheric        class="a-plus-plus">F Region Induced by a HF
           Heater Wave at Frequencies Near the Fourth Electron Gyroharmonic
    • Abstract: We present the results of multi-instrument studies of the phenomena in the high-latitude ionospheric F region stimulated by high-power HF O-mode radio waves injected towards the magnetic zenith when the ratio of the heater frequency to the cutoff frequency of the F2 layer is near the fourth electron gyroharmonic. Based on the stimulated electromagnetic emission (SEE), spectral observations in the kilohertz and hertz frequency bands of detunings relative to the heater wave frequency, the behaviors of different parameters of the ionospheric plasma and small-scale artificial field-aligned irregularities are compared and analyzed. The coexistence of the thermal (resonance) parametric instability (TPI) and parametric decay (striction) instability (PDI) was found in the vicinity of the fourth gyroresonance harmonic.

Along with the general overview of the respective methods, we perform comparative critical analysis of some of them from the viewpoint of their feasibility and requirements to OCT systems destined for combining the above-mentioned different image modalities.

  • Switching of Microwave Radiation Storage and Output Modes in
           Superconducting Resonance-Cavity Compressors with an Interference Switch
    • Abstract: We propose a commutator for the interference switch of microwave electromagnetic radiation on the basis of a waveguide H-junction made as a cavity with tunable parameters, which is connected to one arm of this junction. The superconducting version of a microwave compressor with such a switch is analyzed. The conditions of effective switch operation in the mode of electromagnetic energy storage and its fast output in the case of controllable manipulation of the Q-factor and resonant frequency of the switching cavity are determined. Estimates of the output parameters of the superconducting compression system are presented for storing- and switching-cavity Q-factors of about 5 ・ 108. The possibility of increasing the radiated power in such a compression system by 40–60 dB for output microwave pulses with durations of about 5–10 ns is demonstrated. Variants of practical implementation of the system are considered.

  • Scattering of a Plane Electromagnetic Wave by a Metal Cylinder with
           Dielectric or Metamaterial Coating
    • Abstract: The problem of diffraction of a plane electromagnetic wave by a perfectly conducting infinitely long cylinder with coating for the cases of the E and H waves is solved. Calculations are performed using the classical electrodynamic solution, which allowed us to develop the spatial field distribution in the covering dielectric layer and compare it with that of the scattered field. To reveal the relation between the characteristics of the scattered field in the far zone and its structure in the dielectric layer, calculations were performed for various relationships between the wavelength and coating thickness. It is shown that the appearance of the sharp azimuthal and frequency irregularities in the reflected field is related to the coating resonances since the azimuthal structure of the scattered field is a function of the spatial distribution of the secondary sources in this layer, whereas the fine structure of the fast variations with frequency is related to variations in the azimuthal distribution of the secondary-source currents. It is demonstrated that using dielectric coatings, one cannot render the metal cylinder invisible in the wide frequency range.

  • Image Correction in Optoacoustic Microscopy. Numerical Simulation
    • Abstract: Optoacoustic microscopy is an efficient method of three-dimensional biomedical visualization, which is based on using single-element focused ultrasonic antennas. Scanning of the studied medium by the focal constriction of an acoustic antenna allows one to retrieve the location of the sources of optoacoustic pulses without using reconstruction algorithms. However, the finite size of the focal constriction results in blurring of optoacoustic images. In this work, we demonstrate the algorithm which is based on calculating the Green’s function for an arbitrary acoustic antenna and allows one to correct optoacoustic images.

  • Electrode Layer in the Electric Field of Deep Convective Cloudiness
    • Abstract: We study variations in the light-ion concentration and space charge density in the atmospheric surface layer during the passage of deep convective clouds. Analysis of the experimental data for 2006–2012 shows matched variations in the positive and negative ion conductivities and both an increase and a decrease (down to zero) in the light-ion concentration at that time. An approach in which the electric field is the external driving force is proposed to describe the properties of the nonstationary electrode layer of the surface atmosphere during thunderstorms. It is shown that the transport of aeroions in the thunderstorm atmosphere is realized by both turbulent flows of air and electric forces, the latter playing a major role. The dynamics of changes in the electrode layer parameters as a function of the field variations has been identified.

  • On Statistical Characteristics of Electric Fields of the Thunderstorm
           Clouds in the Atmosphere
    • Abstract: A series of features of the spectral characteristics of thunderstorm-cloud field perturbations is specified on the basis of long-term ground-based measurements of the electric field at remote locations. A significant increase in the spectral density of the electric-field variations during the thunderstorm has been observed. Maximum increase due to the pulsed field component, which is related to the lightning discharges, is observed in the fluctuation-period range from tens of seconds to several minutes. A significant increase is also observed in the range 0.5–1.5 mHz (10–30-min periods) in which the spectral density is increased by more than a factor of 104, whereas the increase factor at the lower frequencies is equal to 100 (about 10 times for the field). Quasimonochromatic components (with 10–20-min periods) in the frequency fluctuation spectra of an electric field of the powerful thunderstorm clouds, which drift by frequency at the cloud initiation, maturity, and dissipation stages are found. It is shown that presentation of the sequence of the pulsed field perturbations related to the discharges in the form of a pulse flow with independent intervals (Poisson flow) agrees with the form of the fluctuation spectrum of the observed field and leads to an estimate of 10 s for the average relaxation (regeneration) time of the field in the thunderstorm-cloud vicinity after the discharge.

  • Dynamics of Undisturbed Midlatitude Atmospheric Electricity: From
           Observations to Scaling
    • Abstract: Long-term dynamics of the electric field of the midlatitude near-surface atmosphere in a wide range of temporal scales is analyzed according to multiyear observatory and seasonal field observations. It is found that the daily dynamics of the aeroelectric field at mid-latitudes most authentically repeats a diurnal variation for the winter months. It is stated that short-period pulsations of the electric field have a self-similar power-law spectrum. Spatio-temporal scales of the self-similarity interval are estimated and the nature of the generalized diffusive process of the aeroelectric pulsation generation is defined. Characteristics of the turbulent ΔE pulsations are analyzed. Estimates of interrelation between the dynamic (fractal dimensions, intermittency indices) and power (degrees of spectral index and structure function) ΔE characteristics are obtained. Mutual correlations between atmospheric electric field variations, vertical atmospheric electrical current density, space charge density, and atmospheric electrical conductivity are studied. It is shown that variations of the light atmospheric ion number density and space charge density are related with variations of the Radon-222 emanations. Spectral analysis of the space charge density variations is carried out. It is shown that the electrodynamic state of the surface atmosphere depends on the convective state of the atmospheric boundary layer.

  • Study of the Evolution of the Electric Structure of a Convective Cloud
           Using the Data of a Numerical Nonstationary Three-Dimensional Model
    • Abstract: Numerical nonstationary three-dimensional model of a convective cloud with parameterized description of microphysical processes with allowance for the electrization processes is considered. The results of numerical modeling of the cloud evolution for the specified atmospheric conditions are presented. The spatio-temporal distribution of the main cloud characteristics including the volume charge density and the electric field is obtained. The calculation results show that the electric structure of the cloud is different at its various life stages, i.e., it varies from unipolar to dipolar and then to tripolar. This conclusion is in fair agreement with the field studies.

  • Electrodynamic Model of the Atmospheric Convective-Turbulent Surface Layer
    • Abstract: We developed a nonstationary electrodynamic model of the atmospheric convective-turbulent surface layer. As a result of numerical calculations, spatio-temporal distributions of the aero-ion concentration, electric field, conduction current density, and space charge density were obtained under various physical conditions. Depending on the flow direction, convective transfer can strengthen or weaken the effect of turbulent mixing on the electrical state of the atmospheric surface layer.

  • Corona Discharge in Clouds
    • Abstract: We present a review of the results of theoretical studies and laboratory modeling of corona discharge initiation in clouds. The influence of corona discharges on the evolution of the cloud microstructure and electrification is analyzed. It is shown that corona discharges are initiated when large-size hydrometeors approach each other, whereas in some cases, corona discharges from crystals, ice pellets, and hailstones can appear. The corona discharges lead to significant air ionization, charging of cloud particles, and separation of charges in clouds and initiate streamers and lightnings. The influence of corona discharges on changes in the phase composition of clouds is analyzed.

  • Flashes in the Middle and Upper Atmosphere Initiated by the Lightning
           Discharges: Recent Results and Future Optical and Spectral Observation
           Methods
    • Abstract: Recent years yielded important experimental results in the field of studying the middle- and the upper-atmospheric discharges initiated by the lightning strokes. These results have been obtained using the most widespread measurement method related to the high-speed high-sensitivity visibleband cameras and the spectroscopy, which is the most rapidly developing method of observation of the upper-atmospheric flashes. Both methods are used during the ground-based, as well as the balloon- and satellite-borne observations. The above-mentioned methods are reviewed in this paper.

  • Numerical Simulation of Thermodynamic, Microstructural, and Electric
           Characteristics of Convective Clouds at the Growth and Mature Stages
    • Abstract: Numerical calculations of convective-cloud formation during unstable atmospheric stratification and background wind are performed using the author’s three-dimensional nonstationary model with detailed allowance for hydrodynamic, thermodynamic, microphysical, and electric processes. Formation of the positive and negative volume electric charges is studied and the electric field is calculated at various cloud-development stages. The obtained electrostatic-field intensity is used for correction of the cloud-particle coagulation coefficient which increases in the presence of the field and the charges. It is found that the precipitation-particle growth time in an intense convective cloud is decreased by 20–30 % due to electric coagulation.
