Abstract

Analytical and numerical analysis of electromagnetic wave propagation in circular waveguides filled with anisotropic chiroplasma media is presented. Emphasis is given to the characteristics of flux density patterns in the waveguide. In the structure of the waveguide, the inner region is assumed to be bounded by Debye boundaries. The characteristics equation for the modes in this waveguide is obtained. The behavior of the dispersion curves and the energy flux are examined numerically. The negative energy flux propagation through the chiroplasma material is confirmed, which clues to exploring the occurrence of negative refraction in chiroplasma medium..
