Electromagnetic scattering from large cylindrically-shaped reflectors by using the characteristic basis function method with analytical basis functions

A new procedure for an efficient solution of the problem of scattering from large cylindrically- shaped reflectors has been proposed in this paper. It utilizes the CBFs that are obtained by applying the SVD (singular value decomposition) procedure to analytically-derived basis functions. These bases, which are constructed by totally bypassing any conventional MoM-type computation, can be used for all angles of incidence and their application leads to a matrix whose dimensions are relatively small.
