a new approach for transient scattering of infinite conducting cylinders- te case 

a new numerical method is presented to solve the time domain electric field integral equation (td-efie) for a two –dimensional conducting scatterer in free space illuminated by a te-polarized gaussian plane wave. in a time domain method of moments formulation (td-mom) of the problem, the free space two dimensional green’s function, the rectangular temporal basis function and the triangular spatial basis function are used. 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.
