EM Scattering by a Lossy Dielectric-Coated Nihility Elliptic Cylinder

The problem of electromagnetic wave scattering by a lossy dielectric coated nihility elliptic cylinder is analyzed by solving the analogous problem of scattering by two lossy dielectric layers elliptic cylinder using the method of separation of variables. The incident, scattered, and transmitted fields are expressed in terms of complex Mathieu functions. Numerical results are obtained for the scattered fields of lossy and lossless dielectric coated nihility circular and elliptic cylinders to show their effect on the backscattering widths.
