Abstract

Time domain electrical field integral equation (TD-EFIE) technique has been proven to be an effective and convenient tool for time domain analysis of various electromagnetic problems [1-4]. It has been applied to many scattering and radiation problems. The most popular method to solve a TD-EFIE is the marching-on in time (MOT) method using triangular patches and vector basis functions proposed by Rao, Wilton and Glisson (RWG) [5]. However, as pointed by many researchers, the TD-EFIE with the MOT method may suffer from its late-time instability. Much work has been done to eliminate the instability [6-11]. Some of them can get satisfactory results, but it may cost more computer time.
