摘要
传统超表面器件可实现的功能较单一，难以满足复杂多变的实际应用需求.针对这一问题，本文提出了一种基于二氧化钒（VO
2
）的多功能可调控太赫兹超表面，该超表面单元由VO
2
与金属组成的2个双裂环、介质层和金属衬底组成.利用VO
2
材料的相变特性以及几何（Pancharatnam-Berry，PB）相位原理，超表面单元可以在低频（0.8~1.2 THz）和高频（1.2~1.8 THz）2个频段上呈现出2种不同的相位分布，实现对反射圆极化波的独立调控.在此基础上，本文排布了3个具有不同功能的太赫兹超表面阵列，分别在宽带范围内产生了携带多拓扑荷数的涡旋波束和偏转涡旋波束，以及在1.2 THz处实现了平面聚焦波束与涡旋波束之间的功能切换.所设计的超表面在动态调控、宽带响应、多功能集成方面表现出优异性能，为光学元件的小型化、多功能化提供新的可能性，在太赫兹通信和自适应光学系统等方面具有潜在的应用价值.
Abstract
The functionality of traditional metasurface is relatively simple
and it is difficult to meet the complex
and changeable practical application requirements. To solve this problem
a multifunctional tunable terahertz metasurface based on vanadium dioxide (VO
2
) is proposed
which consists of two double split rings made of VO
2
and metal
a dielectric layer
and a metal substrate. Based on the phase transformation characteristics of VO
2
materials and the pancharatnam-berry phase principle
the metasurface unit can present different phase distributions in the two frequency bands of low frequency (0.8~1.2 THz) and high frequency (1.2~1.8 THz)
and realize the independent regulation of the reflected circularly polarized wave. On this basis
three terahertz metasurface arrays with different functions are arranged to generate vortex beams and deflected vortex beams with multi-topological charges in the broadband range
as well as to realize the functional switching between the planar focused beams and the vortex beams at 1.2 THz.The proposed metasurface exhibits excellent performance in dynamic regulation
broadband response
and multi-functional integration
and provides new possibilities for miniaturization and multi-functionalization of optical components. It has potential application value in terahertz communication
adaptive optical systems
etc.
