A Compact Three‐Layer VO2‐Integrated Reflective THz Metasurface With Switchable Half‐Wave‐Plate and Quarter‐Wave‐Plate Responses

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
A switchable terahertz polarization conversion metasurface is demonstrated, utilizing the insulator‐to‐metal phase transition to achieve binary functionality within a single device. By toggling between material states, the metasurface provides high‐performance linear‐to‐circular (LTC) conversion in the insulating phase and linear‐to‐linear (LTL) cross ...
