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.
