Abstract
In this paper, magnetic field integral equations (MFIE) are applied to simplify the complex computation caused by the calculation of shadowing effect in the common iterative physical optics method (IPO). Furthermore, in order to avoid the inverse operation of large matrix in the discretization of MFIE, three-dimensional point functions are applied as the weighting functions while RWG (Rao-Wilton-Glisson) functions act as the basis functions. The whole algorithm of the new method is presented and its validity is convinced by the numerical results, which agree well with the experimental value.
