An iterative solution approach of the magnetic field integral equation for scattering computations

A simple iterative solution of the magnetic field integral equation (MFIE) for scattering computations at perfect electrically conducting (PEC) objects is investigated. The proposed method uses pulse basis functions and point-matching for integral evaluation together with several concepts as utilized in the iterative physical optics (IPO) approach. Furthermore, a special correction scheme for the stabilization of the solution is introduced and tested. It is found that good approximate solutions can be obtained, which are considerably more accurate than asymptotic solutions and less computer intensive than full wave numerical methods.
