Abstract

Optical devices for terahertz wave band from 0.1 to 10 THz are rapidly expanding and require better designs. This paper proposes and designs a parallel plate lens with metal hole array for the terahertz wave band. The fast wave effect is due to the parallel plate. For this lens, the parallel plate spacing and hole array dimensions control the phase velocity and the focusing effect. It is not necessary to control the phase through the lens shape, which is flat, itself. The periodic analysis model extracted from the full model confirms the phase control by the metal hole array dimensions. The periodic model can be used for efficient iterative design. The full wave analysis results are also obtained by ANSYS HFSS and the focusing effect is confirmed. Phase control using both the parallel plate and the hole array enhances the focusing effect over the focusing effect controlled only by the metal hole array dimensions.
