✦ Synopsis

In this paper, a fast algorithm that can be used to sol¨e the time-domain integral equation of transient wa¨e fields is presented. The technique discretizes the time-domain electric-field integral equation ( ) ( ) TDEFIE by means of the marching-on-in-time MOT method. The ( ) fast Fourier transformation FFT is efficiently employed to accelerate the recursi¨e computation of the unknown current coefficients, and to reduce the memory storage requirement in the MOT method. Se¨eral results are presented to demonstrate the efficiency, capability, and accuracy of this technique.
