Calculating Periodic Structures Based on Ideally Conductive Squares
Journal of Communications Technology and Electronics - Tập 65 - Trang 1374-1378 - 2021
V. I. Ponomarenko, I. M. Lagunov
The applicability of the method for solving the problem of diffraction by resistive gratings, based on solving the problem of exciting the Floquet channel by current elements to the calculation of structures with planar ideal gratings, is shown. A quasi-static approximation formula is obtained for the effective dielectric constant of a flat single-layer grating based on perfectly conducting square...... hiện toàn bộ

Excitation of a cylindrical microstrip structure with arbitrarily shaped printed elements by a plane wave
Journal of Communications Technology and Electronics - Tập 56 - Trang 939-946 - 2011
A. E. Svezhentsev, V. V. Kryzhanovskii
The problem of excitation of a cylindrical microstrip structure by a plane wave is considered. The structure is a printed element on a circular dielectric substrate containing a coaxial metal cylinder. In the scattering regime, the structure under study adequately simulates a cylindrical microstrip antenna operating at resonance frequencies. The printed element is equivalent to the radiator of thi...... hiện toàn bộ
Plasmon Resonances in a Star-Shaped Golden Nanocylinder
Journal of Communications Technology and Electronics - Tập 67 - Trang 34-39 - 2022
A. P. Anyutin
Two-dimensional problem of diffraction of a plane electromagnetic TM wave by a cylindrical golden 2D nanostructure is considered. The contour of the cross-section of this structure is a star-shaped curve. The spectra of the scattering cross section and scattering pattern are calculated using a rigorous numerical method in the light wavelength range 400 nm < λ < 900 nm. The influence of the medium ...... hiện toàn bộ
Analysis of the possibilities to determine lunar soil characteristics with the help of bistatic radar

Influence of Geometric Parameters and Permittivity of Stripline Filters on Resonator Coupling Coefficients
Journal of Communications Technology and Electronics - Tập 63 - Trang 254-263 - 2018
A. V. Zakharov
It has been proved that electromagnetic coupling coefficients K of resonators in stripline filters with homogeneous dielectric depend only on geometric parameters of the filter designs and are independent of relative permittivity εr (if the dielectric is two-layer, coefficients K depend only on geometric parameters of the filter designs and ratio εr2/εr1). It has been shown that the revealed earli...... hiện toàn bộ
Numerical Analysis of X-Ray Diffraction Reflection Spectra of AlGaAs/GaAs Superlattices Depending on Structural Parameters
Journal of Communications Technology and Electronics - Tập 66 - Trang 348-353 - 2021
D. V. Ilinov, A. D. Shabrin, A. E. Goncharov, D. A. Pashkeev
In this paper, we study the properties of X-ray diffraction reflection spectra of multilayer periodic AlGaAs/GaAs heterostructures depending on the thickness and composition of the layer material and number of periods. The number and intensity of additional diffraction maxima on the rocking curves are shown to increase with an increase in the layer thickness and number of periods. The layer compos...... hiện toàn bộ
Nonreflecting impedance planes and plane figures
Journal of Communications Technology and Electronics - Tập 60 - Trang 55-57 - 2015
B. Z. Katsenelenbaum
It is demonstrated that, when the function describing the impedance distribution on a plane belongs to a certain class, a wave normally incident on the plane is diffusively scattered and absorbed rather than reflected. When the contour of a finite plane segment satisfies a certain condition, a wave is not reflected by this segment. Such plane figures can provide for antiradar protection. In partic...... hiện toàn bộ
Generalized concatenated system with embedded space-time codes for MIMO systems
Journal of Communications Technology and Electronics - Tập 59 - Trang 1489-1500 - 2014
A. A. Kreshchuk, V. V. Zyablov
Multiple-input multiple-output systems are communication systems employing multiple transmitting and receiving antennas. In the present study, a new generalized concatenated signal-code construction is proposed. Its inner codes are embedded Golden codes, and its outer codes are products of Reed-Solomon codes. New algorithms for decoding inner codes, outer codes, and the generalized signal-code con...... hiện toàn bộ
