Abstract :
Microstrip elements are widely used to realize transmission lines, antennas, and filters. Not surprisingly, a multitude of computational schemes for analyzing microstrip structures have been studied; among them, the finite-difference time-domain algorithm dominates. In recent years, time domain integral equation (TDIE) methods however have been receiving increasing attention. In this paper, a transient electric field integral equation (EFIE) pertinent to the analysis of microstrip structures is established and a marching-on-in-time (MOT) algorithm for solving this EFIE developed. Compared to earlier MOT schemes, the proposed algorithm requires no analytic approximation of the Green´s function kernel and therefore can be considered numerically exact.
