Abstract

Finite element analysis, based on the vector H-field formulation and incorporating the perturbation technique, is used to calculate the complex propagation characteristics of metal-coated dielectric waveguides at THz frequencies. The propagation and attenuation characteristics of the surface plasmon modes at the metal/dielectric interfaces are presented. The effects on the modal properties of metal-clad dielectric guides with the cladding thickness and the formation of the supermodes due to the coupling between the surface plasmon modes in the presence of different surrounding materials are also investigated.
