The eigenequation of a circular chiral ferrite dielectric waveguide is deri
ved. The effects of chiralities in the core and cladding on the cutoff, the
dispersion characteristics, and the field distributions are investigated.
The results show that, not only the cutoff frequencies, but also the disper
sion curves of HE and EH modes with the same mode number separate, and the
chiralities in the core and cladding have different effects on the cutoff a
nd dispersion characteristics. (C) 2001 John Wiley & Sons, Inc.
