摘要：

An efficient time-domain fast dipole method is proposed to accelerate the time-domain volume-surface integral equation for analyzing the transient electromagnetic scattering from composite conducting-dielectric targets with arbitrary shape and inhomogeneity. This scheme is based on the equivalent dipole moment and the Taylor series expansion of the transient far-field. The computational complexity and memory requirement of the proposed algorithm can be reduced considerably by embedding the fast algorithm in a hierarchical framework. Several numerical examples are presented to demonstrate the accuracy and efficiency of the proposed method.
