Abstract

The propagation property of metal wires terahertz waveguides is studiedand simulated under the framework of the Sommerfeld model. The groupvelocity dispersion, attenuation amplitude, transverse magnetic mode andpropagating energy have been obtained by numerically solving the complexeigenvalue equation for the propagation constant. It is found that thegroup velocity dispersion and attenuation amplitude decrease with theincreasing radii of metal wires. The energy power within the dielectriclayer increase with the increase of radiation frequency.
