| 摘 要： | 由于常用的高频近似法和数值方法难于求解较复杂目标的电磁散射问题，故提出一种将迭代物理光学法（ＩＰＯ）和矩量法（ＭＯＭ）相结合计算二维开槽电大目标电磁散射的混合方法．该方法根据等效原理将原问题进行分解，分别采用迭代物理光学法和矩量法计算槽缝填充的电大目标散射场和槽缝散射，并应用广义网络原理处理口径耦合问题．数据结果表明这种方法是精确和高效的．

| Abstract: | The electromagnetic scattering characteristics of two dimentional large boides with cracks on their surfaces have been calculated by the hybrid method. This technique employs iterative physical optical method (IPO) for the scattering from the large bodies with the cracks filled with perfect conductors and the moment method (MOM) to characterize the cracks, and the generalized network principle is then used to combine these two methods. Some numerical results have been obtained which demonstrate the accuracy and efficiency of the technique. |
