Retarded-Time Potentials Due to Impulsively Excited CRWG Basis Functions

Abstract

A scheme to evaluate the time samples of the retarded-time potentials due to impulsively excited curvilinear Rao-Wilton-Glisson (CRWG) functions is presented. The retarded-time potential integrals on the surface of the CRWG functions are reduced to line integrals using the Radon transform interpretation. The resulting line integrals are calculated using the suitable order Gauss-Legendre quadrature rule (GLQR). The numerical examples that demonstrate the accuracy and validity of the proposed scheme are presented.
