Abstract

In this work, we proposed a switchable metasurface based on phase transmission material of vanadium dioxide (VO₂) with metal and insulation mode. Simulation results demonstrated that the metasurface can switch perfectly at frequencies of 1.89 THz and 2.67 THz from two perfect absorbing peaks to a reflecting peak and a transmitting peak. When VO₂ serves as metal mode, there were two absorption peaks of 99.93% and 99.92% respectively. When VO₂ serves as insulation mode, the reflection and transmission magnitudes were 92.50% and 90.50% respectively. Simultaneously, the structure was insensitive to the incident angle from the simulation result. The proposed metasurface could therefore provide potential application prospects for the terahertz band switcher or sensor.

采用相同频率的二氧化钒可切换吸收、反射和透射超表面

在这项工作中，我们提出了一种基于二氧化钒(VO2)相传输材料的具有金属和绝缘模式的可切换超表面。仿真结果表明，该超表面可以在1.89 THz和2.67 THz频率下从两个完美的吸收峰切换到一个反射峰和一个发射峰。当VO2为金属模式时，有两个分别为99.93%和99.92%的吸收峰。当VO2为绝缘模式时，反射和透射幅度分别为92.50%和90.50%。同时，仿真结果表明该结构对入射角度不敏感。因此，所提出的超表面可以为太赫兹波段开关或传感器提供潜在的应用前景。

期刊介绍： Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover: • Novel micro and nanostructures • Nanomaterials (nanowires, nanodots, 2D materials ) and devices • Synthetic heterostructures • Plasmonics • Micro and nano-defects in materials (semiconductor, metal and insulators) • Surfaces and interfaces of thin films In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
