Jg. Xiao et al., FIELD ANALYSIS OF A GENERAL CHIRAL PLANAR WAVE-GUIDE, International journal of infrared and millimeter waves, 18(4), 1997, pp. 939-948
The propagation characteristics of general chiral planar waveguides ar
e presented. This is the first time the eigen equation is given in a s
imple formulation. The results indicate that there are two types of fi
eld distribution which is related to the working wavelength and chiral
admittance. When the chiral admittance is larger than a certain value
, the fields of one kind of circularly polarized wave in the core beco
me exponentially damping in the transverse direction.
