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

The total reflection characteristics of plane waves from the interface including a chiral medium have been studied with complex chiral mater ial parameters. The possible values of chirality admittance zeta(c) ar e determined for left-circularly polarized (LCP) and right-circularly polarized (RCP) total reflections at fixed incident angles from an int erface 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 mod es can be totally reflected for any incident angle theta. It is demons trated that for xi(1) = Re(zeta(c)) > 0, total reflection is preferred for LCP mode whereas RCP total reflection is favored for zeta(1) < 0.
