A plane-wave scattering problem by a dielectric cylinder buried beneath a rough surface is here considered. An analytical solution is proposed, employing spectral representation of the scattered elds. The surface roughness is dealt with by means of pertubation method, i.e. elds expression are the sum of an unperturbed term relevant to a at sur- face, and of a rst-order term due to rough prole. Solutions may be obtained both in near- and far- eld region, and in case of TE or TM polarization. Numerical results are given for a cylinder buried un- der a surface with sinusoidal prole.

Abstract
A plane-wave scattering problem by a dielectric cylinder buried beneath a rough surface is here considered. An analytical solution is proposed, employing spectral representation of the scattered elds. The surface roughness is dealt with by means of pertubation method, i.e. elds expression are the sum of an unperturbed term relevant to a at sur- face, and of a rst-order term due to rough prole. Solutions may be obtained both in near- and far- eld region, and in case of TE or TM polarization. Numerical results are given for a cylinder buried un- der a surface with sinusoidal prole.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
