Abstract

A marching-on-in-time (MOT)-based time domain integral equation (TDIE) accelerated scheme is presented for the analysis of transient scattering from complex objects. The scheme employs the plane wave time domain algorithm (PWTD) to realize the efficient and fast evaluation of 3D transient wave field, thus reduce the computational complexity of MOT. The presented PWTD-enhanced MOT scheme renders feasible and rapid integral equation based analysis of transient scattering phenomena involving electrically large surface. The numerical results that demonstrate the accuracy and efficacy of this scheme are given in this paper.
