Low cost and long-focal-depth metallic axicon for terahertz frequencies based on parallel-plate-waveguides
Abstract In this work we demonstrate a triangular surface lens (axicon) operating at frequencies between 350 and 450 GHz using parallel-plate-waveguide technology. The proposed axicon offers longer focal depth characteristics compared to conventional plastic lenses, surpassing common TPX lenses by o...
