“…Besides MGs, transmittance in decibels is calculated as (5). Testing has shown that all three closed-form expressions (3)-(5) provide sufficiently high accuracy of analytical data in most practical cases, except for two points: m, m, and m; m, m, and m. Such disagreement of analytical and numerical data is explained by very low values of in the operating frequency range.…”

In this paper, the results of theoretical and experimental studies of 1-D metallic gratings for mesh polarizers used in radar and communication engineering are presented. To calculate the transmission characteristics of gratings with rectangular lamels, fabricated by the technology of double-side jet etching, a 2-D finite-element model with Floquet periodicity conditions is developed with the parameters of the signal at the grating input taken into account. Simple design equations are obtained by using regression analysis and the results of numerical modeling. Both numerical and analytical models are tested experimentally. The influence of three basic dimensions of the grating on the level of transmitted power is established for the -polarized electromagnetic waves.

“…One group of these components are the structures where cylindrical posts of arbitrary shape are applied to obtain desired scattering parameters [1][2][3][4][5][6][7][8][9][10][11][12]. Generally, in the analysis of these components open and closed problems can be distinguished.…”

“…In the closed problems the result of the analysis are scattering parameters of waveguide junctions or resonant frequencies of resonators loaded with cylindrical objects. Rectangular waveguide junctions and circular cavities consisting of single or multiple cylindrical posts are applied to filters [7,8], resonators [9], phase shifters [10], polarizers [11], multiplexers or power dividers [12].…”

Abstract-This paper presents a new hybrid finite-difference frequency domain -mode-matching method (FDFD-MM) for the analysis of electromagnetic wave scattering from configuration of metallic or dielectric cylindrical posts with arbitrary cross-section. In our approach each scatterer is treated as an effective circular cylinder represented by impedance matrix defined in its local coordinate system. In order to obtain the scattering parameters of arbitrary configuration of objects in global coordinate system an analytical iterative scattering procedure (ISP) is applied. This work is an extension of our previously published results, where our consideration were limited to two dimensional (2D) problems with TM excitation. In this paper, we extended our analysis to two-and-a-half dimensional (2.5D) problems. The accuracy of the proposed method is presented and discussed. To verify our approach some numerical examples are presented. The obtained results are compared with the results published in literature and the ones obtained from own measurements and commercial software.
