Reflection and Transmission of Electromagnetic Plane Waves from a Uniaxial Chiro-Omega Slab

摘要

Chiro-omega medium is a combination of the reciprocal chiral and omega media, andcan be obtained by mixing helical and Omega-shaped wire elements in the host medium. In this article the most general uniaxial chiro-omega medium is studied. The solutions for the dispersion equations and corresponding eigenwaves are derived. Transmission and reflection properties of a chiro-omega slab at a normal incidence are studied, and the polarization, direction of the polarization ellipse, and relative powers of transmitted and reflected waves are given. The results are applied to find suitable parameters for designing a polarization transformer. These results are compared with those obtained in earlier studies on wave propagation in a free uniaxial chiral space, where the effect of the boundaries of a proposed polarization transforming device have been neglected.
