Abstract

The phase velocity of plane waves propagating in an isotropic chiral medium can be simultaneously positive for left‐circularly polarized light and negative for right‐circularly polarized light (or vice versa). The constitutive parameter regimes supporting this phenomenon are established for nondissipative and dissipative mediums. The boundary between positive‐ and negative‐phase velocity is characterized by infinite phase velocity. © 2007 Wiley Periodicals, Inc.

## Abstract The propagation of plane waves in an isotropic chiral medium (ICM) is investigated. Simple conditions are derived—in terms of the constitutive parameters of the ICM—for the phase velocity to be directed opposite to the direction of power flow. It is demonstrated that phase velocity and
