Abstract
A spectral-domain method, for the solution of the two-dimensional electromagnetic plane-wave scattering by a finite set of perfectly conducting or dielectric cylinders buried in a dielectric half-space, has been developed. The scattered field is represented in terms of a superposition of cylindrical waves, and use is made of the plane-wave spectrum to take into account the reflection and transmission of such waves by the interface. The problem is solved for both the near-and the far-field regions, for TM and TE polarizations. The validity of the approach is confirmed by comparisons with results available in the literature. The technique is applied to scatterers of arbitrary cross-section simulated by a suitable configuration of circular cylinders. Our method is employed to study the scattering from buried objects of a pulsed plane wave, that may have a rather general shape in the time domain, by performing a sampling of the incident-field spectrum, and solving the problem in the frequency domain.
