We proposed a vanadium dioxide (VO 2 )-integrated multi-functional metamaterial structure that consists of three metallic grating layers and two VO 2 films separated by SiO 2 dielectric spacers. The proposed structure can be flexibly switched among three states by adjusting temperature, incident direction, and polarization. In state 1, the incident wave is strongly transmitted and perfectly converted to its orthogonal polarization state. In state 2, the incident wave is perfectly absorbed. In state 3, incident wave is totally reflected back. The working frequency of the multi-functional metamaterial can be arbitrarily tuned within a broad pass band. We believe that our findings are beneficial in designing temperature-controlled metadevices.

用于太赫兹波操纵的多功能二氧化钒集成超材料

我们提出了一种集成了二氧化钒(VO 2)的多功能超材料结构,该结构由三个金属光栅层和两个被SiO 2介电垫片隔开的VO 2膜组成。通过调节温度,入射方向和极化,可以在三种状态之间灵活切换所提出的结构。在状态1中,入射波被强烈传输并完美地转换为其正交极化状态。在状态2中,入射波被完全吸收。在状态3中,入射波被完全反射回去。多功能超材料的工作频率可以在较宽的通带内任意调节。我们相信我们的发现对设计温度控制的元设备很有帮助。
