THz Field Enhancement by Antenna Coupling to a Tapered Thick Slot Waveguide

We demonstrate experimentally the coupling of a THz beam into a laser-machined double-tapered thick slot waveguide operating between 0.3 and 2 THz. Simulation reveals that the THz field generated by a standard photoconductive antenna coupled to an undoped aspheric HRFZ-silicon focusing lens can be e...
