摘　　要：本文讨论了用时域有限差分法计算E平面波入射到任意截面柱体时的二维电磁散射近场问题。先计算了完纯介质柱体的几个典型的例子,与文献[1]中的实验结果及其它数值结果相比较,证明所用方法的有效性。然后,计算了有耗体和有耗介质覆盖导电体的电磁散射近场。The near fields of electromagnetic scattering by lossy cylinders with arbitrary cross sections were studied using time—domain finite difference (FD—TD) method. Several typical examples of perfect dielectric cylinders were considered at first. The results were compared with the existing results from other mumerical methods and experiments. It verified the validity of FD—TD method in solving such kind of problems. Then, the scattered near fields by lossy cylinders and by lossy material covered conductor cylinders were also calculated, the work may be of values for the research of the effects of buildings on EM waves.
