“Mathematical modeling of multi-layer polarizers on meander lines” When considering the problem of transformation of electromagnetic field of the linear polarization within the field of elliptic polarization, and vice versa, the multi-layer … |
The problem of flat wave diffraction on a multi-layer meander polarizer is solved in a strict electrodynamic setting; to approximate the required electrical current a full orthogonal system of basis functions has been proposed; for the one- and four-layer …
When considering the problem of transformation of electromagnetic field of the linear polarization within the field of
elliptic polarization, and vice versa, the multi-layer meander polarizers (MMP) in the wide band are of practical interest. [1] shows the solution of the boundary problem of electrodynamics as well as defines the scattering signatures of a flat wave on one polarizer layer.
For a number of layers however an approximate approach based on neglect of interaction between the layers as per the highest type of spatial harmonics has been used. This allowed to find the scattering matrix of a multi-layer polarizer via the scattering matrix of one of its layers. The problem related to estimate of applicability boundaries of such approach has not been con-sidered…

In section of “Publications-Dissertations” the “Metal-dielectric structures in antenna arrays, radio-absorbing coatings and near-omnidirectional radiators” dissertation is published.
Author: I. V. Sutyagin.
The aim of the dissertation is to develop electrodynamic-level mathematical models describing printed-circuit radiators of an irregular shape within an antenna array that make it possible to analyze the radiation pattern characteristics of separate printed-circuit radiators located on finite screens of an irregular shape and mathematical models for analyzing the characteristics of ultrawideband ribbon antenna arrays with wide-angle scanning.
