一种磁场积分方程奇异性处理的有效方法
An effective method to solve the singularity of magnetic field integral equation
摘要
Abstract
In order to solve the problem of the low precision of electromagnetic scattering characteristic,which was calculated by magnetic field integral equation,the singularity of the magnetic field integral equation was analyzed,the inner layer integral singularity of the equation was extracted and processed,and the outer layer integral singularity in calculation was solved with the simple method of integral domain transform in this paper.Then the Radar Cross Section could be calculated accurately with MFIE based on MOM.The resulting RCS was in good agreement with that was obtained by the electric field integral equation,and the error was lower than 0.5 dB.The effectiveness of the method was demonstrated by numerical results.关键词
