N2 - A hybrid technique combining the shooting-and-bouncing-ray (SBR) method and the method-of moments (MoM) is presented for analyzing scattering by large conducting bodies having small, inhomogeneous protrusions. In this technique, the MoM with an approximate Green's function is used to characterize the small protrusions, yielding an admittance matrix, which, when multiplied with the incident field on the protrusions, yields the currents induced on the protrusions. The incident field in the presence of the large bodies is calculated using the SBR method. The field radiated by the currents on the protrusions is also calculated using the SBR method with the aid of reciprocity. Furthermore, an iterative approach is developed, which can reduce the error introduced by the use of the approximate Green's function. Numerical results are given to demonstrate the efficiency, accuracy, and capability of the hybrid technique.
