Plane-wave scattering by a dielectric circular cylinder parallel to a general reflecting flat surface

We present a generalization of a method developed for treating the plane-wave scattering by a perfectly conducting circular cylinder in front of a plane surface to the case of a generic dielectric circular cylinder. Thanks to this formulation, the problem can be treated in a very efficient way for both the near and the far field, and an accurate determination of the field inside the cylinder is possible. Numerical results and comparisons with other methods are presented.
