Photoconductive Terahertz Antenna with Radial Symmetry

The use of coaxial waveguides with terahertz pulses requires the difficult excitation of the radially polarized fundamental mode of the waveguide. We propose a radially symmetric terahertz antenna and present simulations predicting the generation of a radially polarized beam.
