摘要/Abstract

摘要： 利用介质半空间格林函数,将一种混合场积分方程(JMCFIE)推广应用到有耗半空间的均匀介质的散射分析中,以减少离散矩阵方程迭代求解时所需的迭代步数,提高矩量法(MoM)对半空间介质目标散射分析的求解效率.数值算例验证了方法的准确性和有效性.

关键词: 有耗半空间, 均匀介质散射, 矩量法, 表面积分方程

Abstract: Electromagnetic scattering of arbitrarily shaped 3-D homogenous dielectric objects located above a lossy half space is investigated.With spatial domain half-space Green's functions surface integral equations are studied to reduce iterations and to enhance efficiency of the method of moment(MoM).An integral equation called JMCFIE is extended to half-space to realize accurate and fast solution.This formulation leads to a well-conditioned matrix equation with RWG basis functions and Galerkin's method.Numerical results demonstrate accuracy and efficiency of the proposed method.

Key words: lossy half-space, dielectric objects scattering, MoM, surface integral equation
