| Abstract: | In view of the late-time instability which occurrs when the time domain integral equation is used to slove the electromagnetic scattering problems of two dimensional conducting objects.We present a method that utilizing error formulation to optimize the averaging scheme’s coefficient.By changing the averaging scheme’s coefficient to achieve the purpose of improve the stability of the late-time. |
