On the scattering by buried objects

The scattering problem by a set of buried circular-cross section cylinders is considered. A scenario with cylinders buried in a dielectric slab between two semi-infinite half-spaces is solved by means of Cylindrical Wave Approach (CWA). The same technique is also applied to the scattering by cylinders under a rough surface of separation between two semi-infinite media. In the latter case, the CWA is combined with a perturbative solution, since small surface roughnesses are supposed. Solutions can be found for both perfectly-conducting or dielectric objects, both in near and far-field region. A finite and arbitrary number of cylinders can be used. Moreover, cylindrical objects with arbitrary cross-section are simulated in the numerical results. © 2011 IEEE
