Abstract

In this work, a new method is presented for analyzing the transient electromagnetic response from conducting wire structures using the time-domain integral equation (TDIE). Instead of the conventional marching-on in time (MOT) technique, this solution method is based on Galerkin's method, which involves separate spatial and temporal testing procedures. Piecewise triangle basis functions have been used for spatial expansion and testing functions for arbitrarily shaped wire structures. The time-domain variation is approximated by a temporal basis-function set that is derived from the Laguerre functions. These basis functions are also used for temporal testing. The method presented in this paper results in very accurate and stable transient responses from wire antennas and scatterers. Representative numerical results are presented and compared with available data.
