Abstract: (3293 Views)
Experience shows that the contact layer is one of the parameters that affect the performance of terahertz waveguides. In this paper, with using of the wave equation, the loss and confinement factor in terahertz waveguides are calculated. The results of this paper show that by changing the thickness of the contact layer, the confinement factor and waveguide loss can be improved. Also, due to lower loss and higher confinement factor, the metal-metal waveguides have better performance rather than semi-insulating surface-plasmon waveguides. The obtained results from simulation in this paper are in good agreement with experimental results.
