Abstract :
A new approach conjugating the compressive sensing (CS) and the Method of Moments (MoM) is proposed and validated in this paper for fast analyzing the monostatic scattering problems. The nonuniform rational B-spline (NURBS) is introduced to MoM for the purpose of reducing the unknowns in the electric field integral equation (EFIE). Meanwhile, the CS theory is utilized to decrease the sampling rate of the incident angles in wide-angle scattering problems. The accuracy and efficiency of the proposed approach are shown by comparing with the traditional MoM using Rao-Wilton-Glisson (RWG) basis function.
