A new robust technique for transient analysis of conducting cylinders - TM case

In this paper, a new robust numerical technique is presented to solve the Time Domain Electric Field Integral Equation (TD-EFIE) via a time domain Method of Moments (TD-MoM) for infinite conducting cylinders in free space illuminated by a TM-polarized Gaussian plane wave. Both of the temporal and spatial basis functions are rectangular. By employing Galerkin´s method in spatial domain and point matching in time domain, it is shown that the time convolution integrals and self terms involved in the formulation can be evaluated analytically to increase the accuracy and the stability of the proposed technique. This possesses the advantage of a simple implementation. Numerical examples are demonstrating the accuracy and efficiency of the proposed method.
