Radiation pattern computation of source and scattering object by one decoupling method

In this paper, radiation pattern of separated source of wire-surface connected structure and object of electrically large size is analyzed, to decouple the MoM and MLFMA region, the source is solved by MoM, object is computed by MLFMA, and the radiation near field of source acts as incident field of the object. With three types of basis functions are used to describe currents on source, numerical results are presented using the proposed method, which have excellent agreements to those from the commercial software.
