The radiation pattern of a circularly-layered dielectric lens is computed using the series solutions and recurrent formulas for cylindrical functions with complex arguments. The Complex Source Point (CSP) beam is taken as a 2D model of a beam field. Unlike the well-known classical approximation for a plane wave scattering from a layered circular cylinder the proposed approach enables one to obtain a numerically accurate solution of the discussed problem.References
