The characteristic basis function method (CBFM) is a kind of direct method for solving EM scattering and radiation problems based on integral equation (IE), the number of unknowns could be dramatically reduced through building CBFs over sub-domains, final matrix equation can be solved by direct method, so it is especially suitable for multiple excitation case. But the filling time of matrix entries...
The efficient calculation of the electromagnetic interactions with dielectric objects is always a challenge to CEM (computational electromagnetics). Among the numerical exact methods, the method of moment (MoM) is considered to be more preferable than finite element method (FEM) and finite difference method (FDTD) for its high precision and discretization on the geometry model instead of the field...
