Abstract
The dispersion properties of guided waves in an anisotropic film sandwiched between a left-handed material (LHM) and a dielectric are investigated in this work. Detailed mathematical derivation of the dispersion relation is presented. Both the anisotropic guiding layer and the LHM are assumed to be dispersive. Many interesting features have been found. The dispersion properties exhibit a slight dependence on the parameters of the anisotropic guiding layer whereas they show a significant change with any perturbation in some of the LHM layer parameters, especially for ω > 5.2 GHz.
