Broadband Terahertz Coding Metasurface Integrated With Bias Circuit

摘要

Terahertz dynamic coding metasurface has always aroused extensive attention for many years. However, complicated bias circuit design still is a significant challenge. Here, we design a terahertz metasurface composed of the unit cells with bias circuit integrated. We have experimentally demonstrated the anomalous reflection of the terahertz metasurface in a wide frequency band (0.32 to 0.49 THz) by employing different coding sequences. This work provides potential applications for the development of interesting dynamic terahertz devices.
