摘　　要：通过建立自由空间内多个导体介质混合目标的理论模型,根据电磁场等效原理和边界条件,建立了求解任意形状导体介质混合目标散射特性的时域电场积分方程(TDEFIE)。导出了TDEFIE的时间步进算法(MOT)矩阵方程,并应用基于隐式MOT算法的TDEFIE对任意形状导体介质混合目标进行了瞬态分析,其数值结果说明了该算法的有效性。The theory modeling of multi-conductor/dielectric in free space is established, and a time-domain electric field integral equation （TDEFIE） for analyzing transient scattering from arbitrarily shaped conductor/dielectric composite objects is presented based on the equivalence principle and boundary conditions. The matrix equation of marching-on in time （MOT） method for solving TDEFIE is deduced. The transient scattering from conductor/dielectric composite objects are analyzed by the implicit MOT method. Numerical results demonstrate the validity and efficiency of the algorithm presented in this paper.
