An Efficient Numerical Algorithm for Solving Scattering and Inverse Scattering Problems of Electromagnetic Waves

Abstract

The scattering of normal incident time harmonic TEM electromagnetic wave by a cylindrical target with axis along z direction is considered. The whole space domain 0 is divided into three connected but non-overlapping sub- domains, the interior region -01 representing the target and possessing a non- orthogonal cylindrical grid system centered in itself, the intermediate region - 02 representing the free space just outside of the target and possessing the same 03 grid system, and the exterior region 03 representing the far field free space but truncated at a large distance away from the target and possessing the standard orthogonal cylindrical grid system.
