矩形涂层板的电磁散射
EM SCATTERING BY RECTANGULAR CONDUCTING PLATE COATED WITH LOSSY DIELECTRIC
-
摘要: 本文讨论了涂覆有耗介质的矩形平板的电磁散射。涂层介质的参数可以任意。表达式中涉及的Maliuzhinets函数的计算,由于采用了多项式近似,避免了复平面内的积分,从而使计算时间大为减少。最后将理论计算结果与实验值相比较,两者吻合得很好。

Abstract: The EM scattering by rectangular conducting flat plate coated with lossy dielectric, whose parameters may be arbitrary, is studied To avoid the complex integral, Ma-liuzhinets functions involved are approximated with close-form analytical expressions so that the computing time is reduced greatly. The results in the paper are in fair agreement with the experimental ones. -
