Abstract

A theoretical investigation of the interaction of electromagnetic waves with a dielectric slab placed in a chiral medium is presented. From the chiral medium either a left circularly polarized (LCP) wave or a right circularly polarized (RCP) wave is obliquely incident on the dielectric slab interface placed in the chiral medium. Two waves RCP and LCP are reflected into the chiral medium and one wave is transmitted into the slab at the first interface. Similarly, Two RCP and LCP waves are transmitted into chiral medium and one wave is reflected into the slab at the second interface. The reflection and transmission coefficients at the chiral-dielectric and the dielectric-chiral interfaces have been formulated and obtained analytically using the transfer matrix technique. Numerical results are presented to explain the effect of the chirality and the incidence angle on the reflection and transmission coefficients and, hence, on the reflected and the transmitted powers. The accuracy of the presented formulation and results has been validated by comparison with other results available in the literature..
