摘要: 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 ζc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 ζc , in which neither LCP nor RCP modes can be totally reflected for any incident angleθ. It is demonstrated that for ζ1=Re(ζc)>0,total reflection is preferred for LCP mode whereas RCP total reflection is favored for ζ1<0.

Abstract: 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 $\zeta$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 $\zeta$= Re ($\zeta$c)>0, total reflection is preferred for LCP mode whereas RCP total reflection is favored for $\zeta$1<0.
