Basis function considerations for the method of moments using the fictitious current model

In the method of moments (MoM) using the fictitious current model (FCM), an impulsive basis function is principally employed to expand the fictitious currents for various electromagnetic scattering problems. In this paper, we introduce the subdomain basis functions and consider the dependence of the solution accuracy and computation time of the MoM-FCM on the basis functions by means of a canonical two-dimensional (2-D) scattering problem.
