摘要

本文提出并验证了一种基于相变材料的元表面滤波器。根据二氧化钒（VO2）的温度相变特性，这种元表面滤波器在温度低于 68 ℃ 时可获得四个滤波带。当温度高于 68 ℃ 时，会产生两个新的滤波波段，并保留原有的四个滤波波段。通过改变温度实现了两种滤波器状态之间的主动调制和转换。此外，这些滤波器波段还具有可调谐性（频率和振幅都取决于温度条件）。这些结果证明了元表面滤波器的可调谐性和温度感应特性。

Verification of a 6G terahertz tunable metasurface filter based on phase change materials and its sensing performance

Here, a metasurface filter based on phase change materials is proposed and validated. Based on the temperature phase transition characteristic of vanadium dioxide (VO₂), this metasurface filter obtains four filter bands at temperatures lower than 68 °C. When the temperature is higher than 68 °C, two new filter bands are achieved and the original four filter bands are retained. The active modulation and conversion between two filter states by changing the temperature are achieved. In addition, these filter bands are able to achieve tunability (both frequency and amplitude are dependent on temperature conditions). These results demonstrate the tunability and temperature sensing characteristics of the metasurface filter.
