摘　　要：基于等效定理和互易性原理研究了两相邻有限长介质圆柱的复合电磁散射问题,推导出该复合散射场的二阶散射场计算公式.将公式所得结果与矩量法结果进行了比较,并分析了两柱距离、圆柱长度和极化状态等参量对复合散射场的影响.Based on the equivalence principle and the reciprocity theorem,the composite electromagnetic scattering from two adjacent finite length cylinders is considered and a solution that accounts for multiple scattering up to second-order is deduced. Numerical results obtained by our formulas are compared with the results obtained by the method of moments. Meanwhile,the dependence of the composite scattered field on the parameters,such as the distance between the cylinders,the length of the cylinders,polarization state and so on,is discussed.
