摘要
将物理光学法和不变量测试方程方法相结合,提出了MEI-PO方法计算电大尺寸物体的电磁散射。首先利用物理光学法代替MEI方法计算部分区域的截断边界条件,然后和其余部分的MEI方法截断边界条件一起,统一计算电大尺寸对象的散射场,数据结果表明,该数值近似算法是有效的。
A hybrid technique to calculate the scattering of electrically large bodies is developed in the paper by combining high-frequency approximation method (physical optical method) and MEI method. Truncated boundary condition of part of domain is calculated by using PO method instead of MEI and the rest of the domain is calculated by using MEI method. The numerical results show the validity of the method.
