Vector circuit method applied for chiral dielectric slab waveguides
Abstract
The analysis makes use of vector circuit modeling of a chiral slab, the method which has been previously applied for calculating reflection and transmission of electromagnetic waves in chiral multilayer structures. After deriving the general eigenvalue equation for the guide and valid for arbitrary boundary impedance conditions on the slab interface, three special cases were analyzed in detail; an open chiral dielectric slab with dielectric half spaces at opposite sides of the slab, a chiral dielectric slab on an ideally conducting surface, and a chiral dielectric slab on an ideal magnetic surface. The theory is supported by calculated dispersion curves indicating the chirality effect on the wave propagation characteristics.
