AN IMPROVEMENT FOR CALCULATIONS OF THE CHARGE TERMS IN ELECTRIC-FIELD INTEGRAL EQUATION
-
摘要: 电场积分方程(EFIE)是求解电磁散射问题时应用最广泛的方法之一。但是,这一方法在用于求解二维TE问题和三维问题时会出现较大计算误差。本文讨论出现计算误差的原因,指出改进电荷项的计算有利于提高计算准确性。

Abstract: Electric-field integral equation(EFIE) method is one of most widely used methods for solving the electromagnetic scattering problems. Unfortunately, inconsistencies in the numerical results are observed when the method is used in the 2-D TE and the 3-D situations. In this paper, the authors try to discuss why the difficulties occurred and point out that the numerical results will be more accurate if the calculations of the charge terms are improved. -
