An analytical-numerical technique for the solution of the plane-wave scattering problem by a set of perfectly conducting circular cylinders, buried in a dielectric slab, is presented. The problem is solved for both TM and TE polarizations, and for nearand far-field regions. The proposed method expresses the scattered fields in terms of cylindrical waves, and exploits the plane-wave spectrum of a cylindrical function to take into account the reflection and transmission through the planar interfaces. Numerical results are reported and the validity of the approach is confirmed by comparison with results given in the literature, showing a good agreement.

Abstract
An analytical-numerical technique for the solution of the plane-wave scattering problem by a set of perfectly conducting circular cylinders, buried in a dielectric slab, is presented. The problem is solved for both TM and TE polarizations, and for nearand far-field regions. The proposed method expresses the scattered fields in terms of cylindrical waves, and exploits the plane-wave spectrum of a cylindrical function to take into account the reflection and transmission through the planar interfaces. Numerical results are reported and the validity of the approach is confirmed by comparison with results given in the literature, showing a good agreement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
