Abstract :
We present an innovative strategy to compute the impedance elements of the MFIE formulation in method of moments (MoM) for low-order basis functions, be it divergence-conforming (RWG) or curl-conforming (nxRWG). Our strategy is based on a new accurate integral singularity extraction that can be applied with most accuracy to compute the impedance elements of either MFIE[RWG] or MFIE[nxRWG]
