摘要

本文提出了一种新型非均匀网格的ＦＤＴＤ法，只需在大小网格连接边界上进行特殊处理，就能较好地解决计算量与精度之间的矛盾；采用本方法分析了柱体目标二维瞬时散射场，并与传统ＦＤＴＤ法作了比较。

Abstract

The new nonuniform mesh FDTD method is presented in this paper. The special treatments of calculation are taken at interfaces between little and large lattice

and the problem of accuracy and amount of computation is solved fairly well. The 2-D transient scattering by cylindrical targets is considered using this method

and compared with the conventional FDTD method.
