二维磁场积分方程奇异点处理的有效方法
Effective approach to deal with the singularity of two dimensional magnetic field integral equation
摘要
Abstract
The method of moment (MOM) solution of integral equation for electromagnetic scattering problems requires calculation of singular integrals, and the calculation of singular matrix element is one of the most important factors that affect the accuracy of method of moment. In this paper, special consideration is presented to evaluate the singular impedance matrix element of the two dimensional magnetic field integral equation(MFIE) with pulse function as basis function and δ function as testing function. The interval is divided into two subintervals, and the calculation of every subinterval is obtained by non-singular traditional method, therefore, the tom/ value of singular matrix element is sum of singular value and two subinterval contribution. The numerical results have demonstrated that accuracy and efficiency are improved by present method for curved scattering body.关键词
