Study on the Dispersion Characteristics of Surface TM Modes in Hollow Slab Waveguide with a Left-Handed Material Cover

Abstract:

The dispersion characteristics of surface TM modes in a hollow slab waveguide which consists of the core and substrate of right-handed material (RHM) and the cover of left-handed material (LHM) are investigated. Normalized frequency, normalized propagation constant and asymmetry measure are introduced to the left-handed material hollow slab waveguide. The dispersion relation is derived by using these normalized parameters, and universal dispersion curves are obtained by solving transcendental dispersion equations analytically. Existence condition and other dispersion characteristics of guided surface TM modes have been discussed in detail for different permittivity of three layers for this left-handed material hollow dielectric slab waveguide.
