Abstract
A terahertz (THz) wire-grid polarizer is designed and demonstrated using an effective fill-factor (EFF) approach. Full-wave numerical simulations are performed to compare the performance of the EFF device with that of a baseline design wire-grid polarizer at two fill-factors (FF). The simulation results predict that the physical effects seen in the baseline design can be realized in the EFF device. This behavior is confirmed in experiments at 275, 530, and 720 GHz.
