Field analysis of a metal-coated planar waveguide with chiral core

Eigenequations for a metal-coated planar chiral dielectric waveguide and a mirror-conjugate planar chiral dielectric waveguide are derived. The eigene quations are given in simple formulations. The results indicate that the pe rfect conductive (or magnetic) boundary can produce mirror-conjugate of chi ral media and the left-handed and right-handed circularly polarized modes c ouple with each other due to the conductive boundary. The propagation chara cteristics of a metal-coated planar waveguide with chiral core are presente d. An interesting phenomenon is observed that the field distributions vary with respect to the operating wavelength.
