Efficient Guiding of Terahertz Wave by Thin Metal Corrugation on Both Surfaces
Thin structured periodic metallic corrugations on both sides of low-loss thin polythene slab are proposed to efficiently guide terahertz (THz) wave based on the surface plasmon polaritons (SPPs). THz time domain spectrometer was used to measure the transmission characteristic. Long-lasting Fabry-Perot resonance modes are demonstrated due to the interferences of the multiple reflected waves.
