This thesis experimentally examines a thick slot waveguide for THz guiding and field enhancement. The waveguide is machined from planar copper sheets using the novel technique of femtosecond laser micromachining. In-plane photoconductive THz coupling to a thick slot waveguide is demonstrated using Discontinuous Galerkin Time Domain (DGTD) simulation. The results reveal positive implications for broadband low-loss/dispersion transmission lines up to 1.5 THz.enTerahertzthzwaveguideradiativein-planeactivecouplingenhancementThesisAvailable to the World Wide WebR.
