Abstract

An efficient method to determine stability and find solutions of the late-time currents is proposed for the time-domain electric field integral equation (TDEFIE) based marching-on-time (MOT) technique. With it, a simple formula is derived to find late-time currents and eigenvalues of the coefficient matrix that then determine the stability of the TDEEFIE method. Numerical examples are then provided to show the effectiveness and accuracy of the proposed method.
