Field Cutoffs of Three-Layer Parabolically DeformedPlanar Chirowaveguides

Abstract

The boundary value problem of a parabolically bent planar waveguide that is completely filled with a homogeneous isotropic chiral material is solved and expressions for the field cutoffs are derived considering special cases. Results are expected to have application in the design of composite chiral media as well as in the tolerance study of planar chiroguides with curvature and flare. The presence of chirality in the cladding introduces some attenuated modes in the waveguide.
