摘要

Electromagnetic fields are expressed in terms of appropriate complex angular and a rigorous solution to the problem of scattering of a plane wave from a chiral lossy metamaterial circular or elliptic cylinder is presented in this paper using the method of separation of variables. The incident scattered as well as the transmitted radial Mathieu functions with expansion coefficients. The incident field expansion coefficients are known, but the scattered and transmitted field expansion coefficients are to be determined. Imposing the boundary conditions at the surface of the chiral lossy metamaterial elliptic cylinder enables the determination of the unknown expansion coefficients. Results are presented as normalized scattering widths for circular and elliptic cylinders of different sizes and chiral lossy metamaterial materials, and for both TE and TM polarizations of the incident wave, to show the effects of these on scattering cross widths.
