Abstract

Here, a 6G terahertz multimodal tunable metasurface based on multiferroic materials is proposed and verified. In the range of 0.3-4.5THz, four absorption peaks based on the bright-dark mode coupling effect between the disc metal arrays were obtained. The absorption performance of this metasurface sample shows geometric parameter selectivity (disc diameter and dielectric layer thickness). In detailed measurements of sensing performance and tunable performance, the metasurface sample demonstrated significant temperature sensitivity. These measurement results provide a foundation for the development of 6G optoelectronic devices based on metasurfaces..
