CHARACTERISTICS OF GUIDED MODES IN UNIAXIAL CHIRAL CIRCULAR WAVEGUIDES

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.
