Abstract

The paper presents analytical investigation of the propagation of electromagnetic waves through chiral/chiral nihility slab waveguide with the emphasis on slow- and fast-waves in the guide. For this purpose, the eigenvalue equation is deduced, followed by the derivation of slow-wave propagation condition. The electromagnetic response of slow- and fast-waves is studied, taking into account a few low-order even modes. It is observed that higher chirality value strongly supports slow-wave propagation for the right-circularly polarized wave. Further, the impedance matching conditions are employed in order to study the behavior of transverse electromagnetic (TEM) modes in the guide. Conditions very close to mode-degeneracy are observed in the case of TEM mode excitation - the phenomenon which may be useful for optical applications.
