Electromagnetic response of a circular db cylinder in the presence of chiral and chiral nihility metamaterials

Abstract

Scattering of electromagnetic plane wave from an infinitely long circular DB cylinder placed in chiral and chiral nihility metamaterials is studied, and the results are compared with that of scattering from DB cylinder placed in free space. The discussion is further extended by considering coating of DB cylinder with chiral/chiral nihility metamaterial. For DB cylinder placed in unbounded free space/chiral/chiral nihility metamterial, only co-polarized scattered fields are obtained, whereas, for chiral/chiral nihility metamaterial coated case, both co- and cross-polarized scattered fields are noted. Numerical results are presented for different values of chirality parameter.
