Abstract :
We design a novel wedge hybrid terahertz (THz) plasmonic waveguide which features longer propagation length and deep-subwavelength mode confinement. It offers improved propagation length, normalized mode area and figure of merit 1.4, 13.5 and 5.3 times compared to the rectangular hybrid THz waveguide.
