【Abstract】 In this paper, relations between the transverse components and the longitudinal ones of electromagnetic fields in rhiroplasma waveguides are derived in a cylindrical coordinate system. The wave equations for the longitudinal components are also presented. By applying the boundary conditions on the wall of a circular waveguide, the characteristic equation for the circular chiroplasma waveguide is obtaind. Propagation constants varying with the normalized radii of the waveguide as well as the chiroplasma parameters are calculated for several lower modes. Some meaningful conclusions are deduced on the basis of numerical results.更多还原
