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). © 2007 Wiley Periodicals, Inc.
