Accurate and conforming mixed discretization of the MFIE
Résumé
In this letter, a novel discretization scheme for the magnetic field integral equation is presented. The new scheme is designated mixed because it uses Rao-Wilton-Glisson functions to expand the current density and Buffa-Christiansen functions to test the magnetic field radiated by the candidate solution. The convergent nature of the proposed mixed MFIE is theoretically proven, and numerical results showing that the proposed method yields more accurate results than the classical one are presented.
