摘　　要：针对传统的矩量法和物理光学混合方法不能有效地考虑大的物理光学区域内部之间复杂的耦合效应问题,将整个目标区域分为多个子区域,并对不同区域分别利用电场积分方程和磁场积分方程来建立方程组.给出了一种分区域迭代的电流基方法来求解各个子区域的表面电流,达到了通过分析各个子区域之间的简单耦合来有效地研究整个大区域的复杂耦合效应的目的.It has been shown that the MoM-PO hybrid method is not effective to dealing with the complex coupling effects in a large PO region. In view of this, the multi-regions are divided on the whole object firstly in the paper. Then, the electric-field integral equation（EFIE） and the magnetic-field integral equation （MFIE） are used to different sub-regions. Furthermore, an efficient sub-region iterative current-based method is introduced to solve the different region＇s current. Therefore, the complex couplings in larger regions are effectively analyzed according to the simple coupling effects among many smaller regions. Finally, two typical numerical examples are given to illustrate the efficiency of the paper＇s method.
