摘要

开发具有高可操作性的6G太赫兹多频段滤波器已成为智能光电器件的研究热点。本文提出了一种6G太赫兹超表面滤波器，并基于金属盘阵列之间的耦合模式测量了4个传输峰。验证了透射峰的幅值点和频率点对结构参数的敏感性。基于GST介电层的相变特性，利用多波段超表面滤波器获得了GST介电层的温度灵敏度和有源可调性。

Optimization and Measurement of a 6G Terahertz Filter Based on the Multi-band Tunable Metasurface and Its Sensing

The development of 6G terahertz multi-band filters with high operability has become a research hotspot in intelligent optoelectronic devices. Here, a 6G terahertz metasurface filter is proposed and measured with four transmission peaks based on the coupling modes between the metal disk arrays. The sensitivity of the amplitude and frequency points of the transmission peaks to structural parameters is confirmed. Based on the phase transition characteristics of the GST dielectric layer, the temperature sensitivity and active tunability are obtained by the multi-band metasurface filter.
