摘要 研究了多个介质-导体组合结构目标的快速电磁散射分析方法。基于矩量法的混合场表面积分方程(JMCFIE)不仅能有效地对具有多区域连接结构的组合目标进行精确电磁建模,而且能够得到一个良好条件数的阻抗矩阵。采用多层快速多极子方法(MLFMA)降低内存需求和计算复杂度,并将多层快速多极子并行化,准确分析了复杂电大尺寸组合目标的电磁散射特性。 A method of analysis of fast electromagnetic scattering problem of composite multi-dielectric and conducting objects is presented in this paper.The combined field surface integral equation(JMCFIE-CFIE) based on the method of moment(MoM) provides an accurate treatment for electromagnetic modeling of the junctions of composite objects with multiple dielectric and metallic regions,on the other hand,the JMCFIE-CFIE formulation can lead to a well-conditioned impedance matrix.The parallel multilevel fast multipole algorithm(MLFMA) is employed to reduce the memory requirements and computational complexity,and some accurate results are presented for the analysis of electromagnetic scattering problem of electrically large complex objects.
