The results of experimental studies of a wideband multimode waveguide Van Attа array constructed on the basis of multimode waveguides in the H-plane (operating when an E-polarized wave is incident) are described. The experimental results were obtained from the monostatic backscattering diagrams of an antenna array in the range of 5–18 GHz in the frequency domain. The experimental monostatic backscattering diagrams (RCS) of Van Atta antenna array shown the good agreement with the calculated one, the half-power width of radiation lobe no less ± 45°. The possibility of frequency extension of a wide-band multimode Van Atta waveguide array due to the excitation of waveguides by ultra-wideband printed dipoles is investigated. The frequency range of the array was able to expand to 6-16 GHz by the antiphase excitation of ultra-wideband printed dipoles.

Technical solution of combination two carried ranges of VHF and UHF in one radio-frequency equipment, with application of the frequency selective structures (FSS) having properties of the artificial magnetic conductor (AMC) is presented. A basis of such system is performance of FSS structures a role of the filter (passing for VHF band antenna array and blocking for UHF band antenna array), allowing to reduce significantly the antenna array cross size and to reduce mutual influence of ranges.

This work considers the process of scattering of nonlinear acoustical waves on cylindrical bodies. The peculiarities of nonlinear wave processes occurring between incident plane and scattered cylindrical waves are described. The inhomogeneous wave equation is solved by the method of successive approximations. An asymptotic expression for the acoustic pressure of a difference frequency wave describes the wave processes that occur. A program has been developed for calculating the scatter diagrams, and an algorithm for its operation is given. Three-dimensional models of the problem of scattering in cylindrical coordinates and the scattering diagram of the acoustic pressure of a differential-frequency wave on a rigid cylinder are presented. The radius of convergence of the used expansion method in a small parameter is determined.

The method of dividing a short nonstationary time series into trend and exponentially modulated harmonic components is proposed. It is based on the SSA (Singular Spectrum Analysis) method. A feature of the method is the transformation of the original series into a new series. This is achieved by removing the trend from the original series and then double-differentiating the remainder. This procedure provides a new series of more contrasting manifestation of the harmonic component and its subsequent selection. The method is tested with polynomial trends of the second and third order. It showed high resolution, including in the presence of weak normal noise, and can be recommended for use in various physical and engineering applications for the study of harmonic processes with small coefficients of attenuation or growth.

Results of compact X-band AESA's radiator and antenna curtain design are presented. Instead of open-end waveguides, printed dipole radiating elements are implemented which increases technological effectiveness of the array antenna and allows its length and weight reduction. The new radiator's topology is presented, results of numerical simulation and calculated characteristics are discussed, and comparison with the currently used open-end waveguide radiator is provided.

In this paper, the experimental study of a metal cylinder with nonlinear loads which covered with metamaterial, is conducted. Previous works showed the possibility of aligning levels of the field scattered from the metal cylinder with nonlinear loads, which is covered with metamaterial, due to the appearing of the nonlinear scattering effect. Frequency characteristics of the scattered field for an experimental model of a metal cylinder loaded with nonlinear structure, which covered with MM, are experimentally received for different radii of cylinder. It’s shown that for investigated "nonlinear" cylinder for some cases the level of the second harmonic may be only on 8 dB lower than the level of the scattered field at the fundamental frequency.
