Paper Abstract

Calculation of the electromagnetic scattering form a buried object, such as a landmine, under acoustic vibration requires a scattering solution for an object beneath an interface with acoustically-induced surface roughness. An analytical solution is presented for the electromagnetic scattering from a dielectric circular cylinder embedded in a dielectric half-space with a slightly rough interface. The solution utilizes the spectral representation of the fields and accounts for all the multiple interactions between the rough interface and the buried cylinder. First order coefficients from the small perturbation method are used for computation of the scattered fields from the rough surface. The derivation includes both TM and TE polarizations and can be easily extended for other cylindrical buried objects. Scattering scenarios are examined utilizing the new solution for a dielectric cylinder beneath both flat and arbitrary surface profiles.
