摘要

An efficient iterative hybrid multilevel fast multipole algorithm (MLFMA) and the physical optics (PO) is presented to efficiently analyze the large size antenna mounted on the electrically large platform, in which, the MLFMA is used to accelerate the impedance matrix–vector multiply procedure of method of moment (MoM) and the PO is employed to simulate the large platform. In this hybrid scheme, to overcome the computational cost required in the evaluation of the electrically large PO region contribution to the MLFMA region, the strategy of the efficient iterative MoM‐PO (EI‐MoM‐PO) is employed. In addition, the electrically large PO region shadowing effect coefficient will be checked before the computation of PO current, then the coefficient will be stored in bit format by using the Bitmap index method which is general enough to reduce the CPU time and memory consumption. The combination of EI‐MLFMA‐PO and Bitmap assists us to construct a proposed method that can reduce the computation cost dramatically and obtain good accuracy. Several examples are demonstrated to validate and prove the accuracy and efficiency of our method compared with the hybrid MLFMA‐PO method in FEKO.
