Terahertz (THz) polarizers, which are commercially available, are made of uniformly and precisely arranged metallic wires. They are fragile, expensive, and highly dependent on the diameter and spacing of the metal wires. Herein, we report a low cost, mass-producible, and highly error-tolerant technology for fabricating flexible and robust THz polarizers with good performance. Carbon fiber-based THz polarizers are fabricated by hot-melt impregnation process and their performances are experimentally demonstrated. THz time-domain spectroscopy is carried out on both flat and curved configurations to measure THz responses of the fabricated THz carbon fiber polarizer (THz-CFP). The results show a high extinction ratio between 20 and 35 dB in the 0.2~1.3 THz range. The insertion losses are lower than 3 dB in the 0.2~1.3 THz range. |
