TOTAL REFLECTION CHARACTERISTICS OF PLANE WAVES AT THE INTERFACE INCLUDING A CHIRAL MEDIUM

The total reflection characteristics of plane waves from the interfac e including a chiral medium have been studied with complex chiral material param eters. The possible values of chirality admittance \zeta_c are determined for left-circularly polarized (LCP) and right-circularly polarized (RCP) total reflections at fixed incident angles from an interface between free space and a chiral medium. It is found that there exists a region of parameter \zeta_c , in which neither LCP nor RCP modes can be totally reflected for any incident angle \theta. It is demonstrated that for \zeta₁ = Re (\zeta_c)＞0, total reflection is preferred for LCP mode whereas RCP total reflection is favored for \zeta₁＜0.
