The characteristics of guided modes in the circular waveguide consist of uniaxial chiral medium have been investigated. The characteristic equation of guided modes is derived. The dispersion curves and energy ∞ux of guided modes for three kinds of uniaxial chiral media are presented. Unusual dispersion characteristics and negative energy ∞ux are found, i.e., backward wave is supported in the uniaxial chiral waveguide.
