N2 - Surfaces of ship, aircraft and vehicle are supposed to be smooth in the calculation of Radar Cross Section (RCS). But there are accessories on their surface in reality. Plates with different accessories were calculated in the paper. Method-of-Moments (MoM) solutions of surface integral equations are especially suited well for scattering computations involving metallic objects. Multilevel Fast Multipole Methods (MLFMM) is used to compute scattering of the complex target. Compared with MoM, MLFMM is efficient and needs less memory. The computational results shows that RCS of a corner reflector loaded with special periodic conducting spheres is reduced.
