N2 - An approach combining the shooting-and-bouncing ray (SBR) method and the method of moments (MoM) is developed for solving electromagnetic scattering problems by large conducting body. In the hybrid technique, an integral equation is first derived for the currents in the entire object, including the entire body and the small structure. The integral equation is reduced to an integral equation over the surface of the small structure. Application of MoM to the equation with Green's function yields an admittance matrix, which characterizes the small structure. When multiplied by the incident field on the small structure using the SBR method, the admittance matrix yields the currents on the small structure, which radiate in the presence of the large body.
