Abstract: The characteristics of guided modes in the circular waveguide filled with uniaxial chiral medium have been investigated. The dispersion equation of guided modes is derived. The dispersion curves, energy flux of guided modes for three kinds of uniaxial chiral media are presented. Abnormal dispersion characteristics and negative energy flux are found, i.e., backward wave is supported in the uniaxial chiral waveguide. It is also shown that the ± m order guided modes have the same propagation constants.

Keywords: Uniaxial chiral medium, chiral waveguide, circular waveguide, energy flux
