【摘要】When calculating electromagnetic scattering using method of moments (MoM), integral of the singular term has a sig-nificant influence on the results. This paper transforms the singular surface integral to the contour integral. The integrand is expanded to Taylor series and the integral results in a closed form. The cut-off error is analyzed to show that the series converges fast and only about 2 terms can agree wel with the accurate result. The com-parison of the perfect electric conductive (PEC) sphere’s bi-static radar cross section (RCS) using MoM and the accurate method validates the feasibility in manipulating the singularity. The error due to the facet size and the cut-off terms of the series are ana-lyzed in examples. 【总页数】7页(386-392) 【关键词】
