摘要

本文首次将微分-Thompson变换应用到电磁散射领域，为解决复杂物体的电磁散射问题提供了一种全新的方法．该方法先利用微分-Thompson变换将形体变换为计算域内的规则形体，再用时域有限差分法在计算域内求出场分布，由变换的一一对应关系直接得出物理域内的场值具体计算实例成功验证了该方法的有效性.

Abstract

The method of differential-Thompson transformation is applied for the first time to the field of electromegnetic scattering by the authors. The complex objects and their comutational region are transformed by Thompson transformation to a regular region. By applving Fnite Difference. Time Domain method

the field distribution in regular region is solved conveniently. The results show that it is superior to the previous approaches.
