Analysis of circular dielectric waveguide with chiral cladding

The propagation characteristics of a circular dielectric waveguide with chi ral media filled in the cladding are investigated. The relation between the cutoff frequency and the chiral admittance, the dispersion curves for some modes with different angular mode numbers and the transverse distribution of fields are presented. Some new features different from the ordinary circ ular dielectric waveguide are resulted. The results show that the cladding chirality may lead to a single-mode operation in the circular dielectric wa veguide.
