Abstract :
We present a novel MoM-MFIE discretization that performs very close to the MoM-EFIE in the electromagnetic analysis of moderately small objects. This new MoM-MFIE discretization makes use of a new set of basis functions that we name monopolar RWG and are derived from the RWG basis functions. We show for curved and sharp-edged objects that the new monopolar MoM-MFIE formulation outperforms the conventional MoM-MFIE with RWG basis functions.
