A Study on Electromagnetic Scattering from Two Adjacent Objects

本文研究了植被环境中相邻两目标的电磁散射问题.在互易原理的基础上,得到了计入相邻目标二次散射的散射场的积分表达式.推导得出了相邻有限长导体圆柱的二次散射场的闭式解,分析计算了其前向散射特性,并与矩量法的数值结果进行了比较.

The problem of electromagnetic scattering from two adjacent objects is considered in this paper. The integral expressions for scattered fields including the second-order scattering terms are given based on the reciprocity theorem. The closed-form solutions are derived for two adjacent cylinders and the forward scattering characteristics are calculated. The results of second-order solutions agree well with the numerical results based on the moment method.
