Scattering of a generic two-dimensional field by cylindrical structures inthe presence of a plane interface

A new method for treating the scattering of a two-dimensional electromagnet ic field, expressed by means of its plane-wave spectrum, by an arbitrary co nfiguration of circular cylinders in the presence of a plane interface betw een two different media, is presented. The proposed method allows us to sol ve the problem for both polarizations and to calculate the scattered field both in the near and in the far zone, Numerical results relevant to vacuum- dielectric interfaces are presented and compared with previous known result s.
