Scattering from a DNG coated PEMC cylinder buried beneath a sinusoidal/flat surface

Scattering of electromagnetic wave from a DNG coated perfect electromagnetic conductor (PEMC) cylinder buried below a slightly rough sinusoidal surface is investigated. This is a generalization of different earlier solved such problems involving PEC/PEMC coated/non-coated cylinder buried below flat/rough surface. The initial reflected and transmitted field from the sinusoidal surface are evaluated using Small Perturbation Method (SPM). All the interactions between the object and the sinusoidal surface have been taken into account using spectral plane wave representation of fields (SPRF). The effect of geometrical and physical parameters on the scattering pattern is observed.
