МЕТОДИ ДОСЛІДЖЕННЯ РОЗСІЮВАННЯ Е-ПОЛЯРИЗОВАНОЇ ХВИЛІ ДВОМА ПРОВІДНИМИ СТРІЧКАМИ З ІМПЕДАНСОМ

A detailed study of the scattering problem of the E - polarized wave from coplanar system of two conductive strips with impedance is presented. The main attention is paid to several important methods of the scattering problem solution, both analytical and direct numerical. Firstly, the classical inte- gral equation method is applied to this problem in order to find the general mathematical model as a system of the first kind singular integral equations. Secondly, the remarkable Rayleigh method is applied to the general correct mathematical model of scattering from electrical narrow strips with imped- ance. As a result, we obtain a solution of the scattering problem in an explicit analytical form, which significantly narrows the frequency range. To find a solution to the scattering problem in the entire frequency range, we ought to apply two well-known and well-grounded direct numerical methods. These are varieties of the mechanical quadratures method with a targeted selection of node points and points of collocations. The influence of the wavelength and the angle of its incidence on the distribution of the current parameter in the structure of two strips is studied.
