文摘

As a marked extension of the traditional MoM-PO (method of moment-physical optics) hybrid method, a new hybridization of PO, SBR, and MoM (MoM-SBR/PO) is presented to calculate the multi-reflection contribution in the PO region efficiently by introducing the method of SBR based on RDN notion, which avoids the time-consuming iterative procedure and the choice of proper Green's function. As compared with the traditional MoM-PO hybrid method, the calculation efficiency of the proposed method is greatly improved, and its validity is verified by numerical results.
