Improvements in the marching-on-in-degree method for time domain integral equations

Marching-on-in-degree (MOD) method has been presented earlier for solving the time domain electric field integral equations in a stable fashion. However, the existing MOD method suffers from low computational efficiency over a marching-on-in-time (MOT) method, particularly for the cases when the MOT method is stable. In this paper, we introduced some techniques to speedup the computation of time domain integration equation (TDIE). Marching-on-in-degree (MOD) method is used in the solving procedure in order to acquire an absolute late-time stable result.
