A nystrom scheme based on cuboid elements for solving Volume Integral Equations

Abstract

Volume Integral Equations (VIEs) are indispensable for electromagnetic (EM) analysis by integral equation approach when inhomogeneous penetrable objects are involved. In the conventional method of moment (MoM) for solving the VIEs, unknown functions are expanded by a well-designed basis function like Schaubert-Wilton-Glisson (SWG) basis function, and a tedious testing procedure is required to transform the VIEs into matrix equations. Although the MoM is dominant, the Nystrom method could be a good alternative because of its well-known merits.
