摘要

本文介绍导电体在不均匀介质复盖下散射问题的混合积分/偏微分方程解法。不均匀介质中的场用偏微分方程模拟

而辐射条件则用积分方程表示。积分方程和偏微分方程都统一用矩量法求解。将二维情况下的数值结果和严格解作了比较

两者符合得很好。

Abstract

A numerical procedure for the solution of scattering problems involving conducting cylin ders of argitrary cross-section shape coated with inhomogeneous dielectric is discussed. The problem is modeled vie a hybrid integral equation/partial differential equation approach.The equations for general three dimentional configurations are reduced to two dimentional cases both for TM and TE illumitions. The method of moments is applied to solve differential equations as well as integral equations. The numerical results are compared with those of the exact solution and good agreement is obtained.
