摘要: 作为传统MoM和PO混合法(MoM-PO)的拓展,提出了一种组合MoM、SBR和PO的混合方法(MoM-SBR/PO)用于计算电大尺寸复杂导体目标的电磁散射。利用基于射线密度归一化(RDN)概念的SBR方法有效地考虑了PO区域之间的多次反射影响,简化了PO区域内的耦合计算,避免了耗时的迭代求解过程和格林函数的选择等难点,提高了计算效率。数值结果验证了该方法的有效性和正确性。

Abstract: A hybridization of PO,SBR and MoM(MoM-SBR/PO) is proposed to calculate electromagnetic scattering of electrical large-size complex conducting objects.By introducing the method of SBR based on RDN notion in traditional MoM-PO hybrid method,the multi-reflection influence in the PO region is efficiently considered to simplify the computation of couple interaction,which avoids the time-consuming iterative procedure and the choice of the proper Green function.The validity of the proposed method is verified by numerical results.
