摘要：

Recent approaches to model corner singularities in electromagnetic analysis require a treatment substantially different from that of edge singularities. In this article, new algorithms are proposed for handling the combination of corner singularities and Green's function singularities on quadrilateral cells in method-of-moments procedures.
