| 摘 要： | 时域积分方程的矩量法是求解瞬态电磁散射的方法之一。研究了基于加权Lagurre函数和RWG基函数分别作为时间、空间基函数的时空矩量法，给出了时域磁场积分方程时空矩量法的全部计算公式，编制了相应串行和并行计算程序。计算结果表明：该方法具有很好的时域稳定特性，为宽带电磁散射分析提供了可能，同时也指出了其应用的局限性，为改进其方法提供了参考。

| Abstract: | Using MOM to solve the time domain integral equation(TD-IE)is one of the important methods for transient EM scattering.The temporal-spatial moment method(TS-MOM)is studied in this paper,which uses weighted Lagurre function and RWG function as temporal basis function and spatial basis function respectively.The calculation formulas of TS-MoM about time domain magnetic field integrate equation are given in details.The serial and parallel calculation programs are obtained.The calculation results show that the T... |
