MFIE can be shown to give more inaccurate results as compared to the EFIE for the solution of electromagnetic scattering problems with RWG functions. This inaccuracy is more evident when the problem involves geometries with sharp edges and tips. The investigation reported in this paper eliminates some of the possibilities that can be considered as the causes of the MFIE inaccuracy. There are other possible causes to consider, such as the quality of the current modeling based on the choice of the basis functions. Indeed, it can be shown that the accuracy of the MFIE is more dependent on the choice of the basis function than the EFIE, and that the inaccuracy of the MFIE can be controlled with the choice of basis functions.
