摘要
在分析电大尺寸物体的电磁散射特性过程中,高频近似方法和数值方法各有其优势和局限性,因此结合两者的优点来解决电大尺寸物体的电磁散射特性将是一条切实可行的途径。文章结合矩量法(MoM)和物理光学法(PO),提出了MoM-PO混合方法来求解电大尺寸物体的电磁散射问题,极大地提高了计算精度,改善了计算速度,为快速有效地解决电大尺寸物体的电磁散射问题提供了良好的途径。MoM-PO混合方法的数值计算结果与传统的MoM计算结果相一致。
In the process of calculating the scattering of electrically large bodies,high-frequency approximation method and numerical method have their respective superiorities and limitations,so it is a feasible method to combine the two methods to calculate the scattering of electrically large bodies.MoM-PO hybrid technique for the calculation of the scattering of electrically large bodies is developed in the paper by combining physical optical method and MoM method,which helps to improve calculating precision greatly and enhance calculating speed.This technique is a favorable approach to calculate the scattering of electrically large bodies.Numerical results are in good agreement with the data got by traditional MoM.
