摘要：

An analytic technique based on spectral plane wave representation of fields (SPRF) for the scattering of a plane wave from a perfectly electric conductor (PEC) cylinder coated with double positive (DPS) or double negative (DNG) materials buried beneath a slightly rough surface is formulated. Small Perturbation Method is used to consider scattering from rough surface. Spectral integrals are evaluated using saddle point method. A comparison with the previously available results has been done for validity. Both TM and TE polarizations are considered to obtain results varying different geometrical and physical parameters.
