ANALYTICAL EVALUATION OF THE MOM MATRIX-ELEMENTS

Derivation of the closed-form Green's functions has eliminated the com putationally expensive evaluation of the Sommerfeld integrals to obtai n the Green's functions in the spatial domain, Therefore, using the cl osed-form Green's functions in conjunction with the method of moments (MoM) has improved the computational efficiency of the technique signi ficantly, Further improvement can be achieved on the calculation of th e matrix elements involved in the MoM, usually double integrals for pl anar geometries, by eliminating the numerical integration, The contrib ution of this paper is to present the analytical evaluation of the mat rix elements when the closed-form Green's functions are used, and to d emonstrate the amount of improvement in computation time.
