Analytical-Numerical Approach for the Solution of the Diffraction by a Thin Dielectric Strip

概要

Approximate boundary conditions are often used to simplify analytical and numerical solutions of scattering problems involving complicated structures. The simplest conditions are the standard impedance boundary conditions applicable at the surface of a lossy dielectric and the related transition conditions modeling a thin dielectric layer as a current sheet. Recently it was suggested by Senior and Volakis that a thin dielectric layer can be effectively modeled by a pair of modified resistive and conductive sheets each satisfying given boundary conditions. In this paper, we shall consider the model of a thin dielectric strip formed by the combination sheets and analyze the H-porarized plane wave diffraction by means of the analytical-numerical approach.
