Abstract :
An analytical study of electromagnetic scattering from a dielectric cylinder buried beneath an acoustically excited interface is presented. The solution utilizes the spectral (plane-wave) representation of the fields and accounts for all the multiple interactions between the 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. Results show that the illumination area should be made close to the size of the buried object of interest to reduce the interference caused by the rough surface
