Zusammenfassung:	In this letter, the equivalent dipole-moment (EDM) method is applied to compute the matrix elements of the method of moments (MoM) via solving the volume-surface integral equation (VSIE). Besides the advantage of reducing the calculation time significantly, this extended method is unnecessary to treat the boundary condition on the surface of dielectric body and easily constructed by using a simple procedure. The proposed approach can be applied if the distance between the source and the testing basis functions is beyond a threshold distance. Numerical results validate the efficiency and accuracy of the generated matrix elements, and the radar cross-section (RCS) has been verified.
