Abstract

The solution of the electromagnetic scattering from target with electrically large aperture cavity is very important and challenging. The electric field integral equation (EFIE) with partial coupling principle presented in this paper to compute equivalent magnetic current on aperture surface is easy to understand and can expand the aperture electrical size greatly. Furthermore, a new usage of multilevel fast multipole algorithm (MLFMA) speeds up the computation.
