Plane Wave Scattering by a Conducting Cylinder Located Near an Interface Between Two Dielectric Half-Spaces: A Perturbation Method

A new and simple method is presented for transverse electric and transverse magnetic plane waves scattering by a perfectly conducting cylinder located near two-media interface. A particular formulation of the surface equivalence principle is employed to form a set of coupled integral equations by considering the interface as a scatterer. In this method, the infinite planar interface is represented by a single equivalent magnetic current which is expressed in terms of the difference in current with cylinder present and the exact solution with cylinder removed. Data for the induced current, near and far field are compared to the results available in the literature for verification.
