Abstract The Higher-Order Method of Moments (HO-MoM) is frequently used to calculate the electromagnetic scattering, because of its high efficient and accurate. Several issues are analyzed in this paper for using the HO-MoM. Firstly, multi-dimension numerical integrations calculated again and again, a novel method is presented in this paper to translate integrations to the product of matrices. When the matrix from MoM filled, it is only needed to calculated the Green’s function at integral nodes. That will reduces CPU time and increase the efficiency of HO-MoM. Secondly, the different methods, used to treat with singular integral or quasi-singular integral, is summarized and estimated.
