摘要：

有关非均匀复杂媒质电磁散射问题的求解是一个复杂而困难的问题,该文利用求解偏微分方程的积分插值法为有关非均匀复杂媒质电磁散射建立差分方程,给出了建模过程并应用于各向异性媒质和旋波媒质电磁散射问题差分方程的构造,并分析了每个方程的计算准确度。一些典型问题的数值计算结果表明了该方法的有效性。

Abstract:

To find solutions of electromagnetic scattering in nonuniform complex media is complex and difficult. This paper establishes difference equations of elec-tromagaetic scattering problem in complex media by integral interpolation me-thod to partial differential equation. The process of modeling and FDE's constru-citron applied in electromagnetic scattering problems in anisotropic and rotary wave zaedia are given. We also analyse in terception errors of difference equations. Numerical results of typical problems show that this method is valid.

Key words: electro-magnetic scattering, finite difference method, partial differential equation
