Correct characterization of guided electromagnetic waves in chirowaveguides of arbitrary cross sections

The eigenvalue problem for the determination of propagating modes in a loss less and homogeneous chirowaveguide of arbitrary cross section is again con sidered in this paper. A corrected analysis of the characteristic equations and the behaviors of the wave modes is made, based on the work by Eftimiu and Pearson [1989] who incorrectly formulated the problem. As an example of the application of the generalized analysis to some specific cases, a circ ular cylindrical chirowaveguide is then considered in the theoretical and n umerical investigations. Through the solution of the characteristic equatio n, a dependency of cutoff wavenumbers of the various eigenmodes upon the ch irality values is found.
