The method of two-dimensional not equidistant antenna arrays design is based on magic squares is proposed. The properties of antenna arrays (directivity pattern, side lobe level, frequency overlap) are studied. An algorithm for providing full frequency coverage of synthesized arrays using magic squares and a method for obtaining arrays of large size using compound squares is proposed.

We develop a cubic nonlinear self-consistent theory of multiharmonic two-stream superheterodyne free electron lasers (TSFEL) of a klystron type, designed to form powerful ultrashort clusters of an electromagnetic field. We have considered plural three-wave parametric resonant interactions of wave harmonics. We used the TSFEL regime in which the first harmonic of a space-charge wave (SCW) is much smaller than the critical frequency of two-stream instability for forming of the powerful ultrashort clusters of electromagnetic waves. Amplitude, phase and spectral analyses of the processes occurring in such devices have been carried out. We found out the conditions needed for the forming of the ultrashort electromagnetic field clusters. We demonstrate the possibility of the ultrashort electromagnetic cluster formation in the multiharmonic TSFEL-type systems.

The dispersion equation describing the eigenmodes of semiconductor cylinder with the layer of two-dimensional electron gas on the side surface (3D+2D-plasma) has been obtained at electrostatic approach. The energy loss of charged particle was found when it moving into external magnetic field that has the strength vector parallel to the symmetry longitudinal axis of the 3D+2D-plasma of cylindrical configuration. The obtained relation allows to find the energy loss in both of a rotary motion of particle around the cylinder and its translational motion parallel to the cylinder generatrix. The effect of non-reciprocity excitation of the eigenmodes of 3D+2D-plasma cylinder was discovered. These modes have identical structures of the field distribution, but differ in the propagation direction along the azimuthal coordinate.

This paper presents novel microwave sensor constructed of simplified three-strip coupled-line section featuring increased sensitivity allowing for measurement of small dielectric material samples for industrial and medical applications. To characterize the sample which at least must be of size of the distance between coupled-strips, a differential excitation is provided to the sensor since the sample significantly more affects the mutual capacitance existing between sensors' coupled strips than the self-capacitance, which is created between the strips and the ground area. The proposed sensor has been theoretically and experimentally investigated and obtained performance has been compared to performance of recently developed two-strip coupled-line sensor. The obtained results proved the correctness and usability of the proposed circuit.

The main purpose of synthetic aperture radar tomography (T-SAR) is to retrieve the vertical distribution of the backscattered power within a range-azimuth resolution cell, allowing three dimensional (3-D) imaging of volumetric targets. The achievable resolution of conventional spectral estimators, used to tackle with the T-SAR vertical distribution estimation problem, highly depends on the span of the tomographic aperture and on the number of acquisitions, reason why, adaptive spectral estimators were introduced in order to ease such limitations. This paper proposes a novel amplitude and phase estimation (APES) -based virtual beamforming approach aimed at resolution enhanced SAR tomography of forested areas, which functions properly using only a few passes and arbitrary constellation geometries, and with imaging capabilities comparable to those gotten from super-resolution compressed sensing spectral estimators with the sum of Kronecker products decomposition technique as a pre-processing step.

In this paper we consider an important practical aspect of texture region detection in remote sensing images. One specific feature of our study is that we assume a processed image noisy with a priori known type and parameters of the noise. Another specific feature is that we try to detect textural regions for a wide variety of textures without having a priori knowledge of their properties. The considered task is solved by means of trained neural networks. In the paper, we analyze the aspects of choosing input local parameters used in detection (recognition) and carrying out training. The verification results provide valuable conclusions for these aspects.
