In this paper,a new and efficient simplificationmethod for symmetry model in computational e-lectromagnetics(CEM) is presented. The numerical method used in this paper is Method of Moments ( MOM) . We can make the induced currentdistribution of a symmetry structure symmetrical bydecompos-ing and restructuring the excitation vector [ V] ,so thatonly a part of the induced current needs to be cal-culated. Consequently,compared to modeling of the whole structure,thesimplification method provides a drastic reduction of unknowns,which saves much more memory resources and computation time. Numeri-cal examples show the reliability and accuracy of theproposed method.
