摘要 基于等效偶极矩法,该文利用快速偶极子法用于快速计算金属介质混合目标的电磁散射。通过分组技术和简单的泰勒级数展开,将远场组之间的矩阵向量积自然地转化为聚集-转移-发散的形式,实现了矩阵向量积的快速计算。另一方面,由于远场组之间的互阻抗元素不用存储,大大降低了内存消耗。在仿真分析中,为了进一步快速计算近场组中的互阻抗元素,还采用了等效偶极矩法。数值结果表明该方法具有较高的计算效率和令人满意的数值精度。 The Fast Dipole Method（FDM） is used for the fast calculation of electromagnetic scattering from composite metallic and material targets,which is based on the Equivalent Dipole-moment Method（EDM）.In the FDM,a simple Taylor＇s series expansion and grouping scheme are used to transform the Matrix Vector Product（MVP） into an aggregation-translation-disaggregation form naturally,which accelerates the MVP remarkably.Further more,the impedance elements related to the far group pairs are not stored,which saves much memory.In addition,the EDM is used to speed up the calculation of mutual impedance elements in the near-field groups.Simulation results are presented to demonstrate the efficiency and satisfactory accuracy of this method.
