ACCURATE COMPUTATION OF THE IMPEDANCE ELEMENTS OF THE MAGNETIC-FIELD INTEGRAL EQUATION WITH RWG BASIS FUNCTIONS THROUGH FIELD-DOMAIN AND SOURCE-DOMAIN INTEGRAL SWAPPING

摘要

We present a new strategy to compute the impedance elements of the Magnetic-Field Integral Equation (MFIE) formulation in Method of Moments (MoM) with a discretization of low-order divergence- conforming basis functions (RWG). The impedance matrix elements are accurately computed by swapping the inner- and outer-integrals in the accurate computation of a MoM-MFIE discretization with low-order curl-conforming basis functions (nxRWG).
