摘　　要：作为光波和电磁波的基本参量之一,偏振态的高效调控是电磁波操纵的核心内容,在成像、通信、显示、光学加密、光力操纵等领域至关重要。超构表面可以在亚波长尺度上操控偏振态,因此成为偏振调控和矢量光束生成的强大工具。本综述首先简单介绍了偏振调控超构表面的基本原理和典型结构,然后重点总结了它在传播方向偏振转换、矢量涡旋光束生成、矢量全息和加密、矢量偏振测量和动态调控等方面的最新应用进展,最后对该领域未来可能的发展方向进行了展望。Significance Electromagnetic(EM)wave front modulation has significance for both scientific studies and industrial applications.However,traditional components for wave field manipulations are often bulky and heavy,which restricts their utilization in miniaturized optical devices and compact detection systems.Metasurfaces are usually composed of arrays of artificial microstructures,also known as meta-atoms,and arranged in a uniform or non-uniform spatial pattern.They can arbitrarily manipulate the amplitude,phase,and polarization of light with sub-wavelength resolution.As a result,metasurfaces have caught much attention in the research on next-generation optical systems.The metasurface design and fabrication has dramatically boosted the employment of optical field modification in compact optical equipment.Metasurfaces are anticipated to break through the bottleneck of conventional optical components and systems,paving the way for miniaturization,integration,and multifunctional processes.While traditional optical elements primarily regulate the optical field by phase accumulation of light along propagation,metasurfaces provide a novel method for controlling the optical field at subwavelength ranges via the interaction between light and meta-atoms.As a two-dimensional planar material with a thin depth profile,a metasurface can generate non-classical phase distributions for transmitted and reflected electromagnetic waves at its interface.Therefore,more flexible control over the wavefront can be realized.Polarization is an inherent property of light waves and electromagnetic waves.It comprises abundant information on substances,which is essential for target detection and identification.The efficient polarization state control is the core content of electromagnetic wave manipulation,which is vital for imaging,communication,display,optical encryption,and optical force manipulation.Due to its ability to manipulate the polarization state on the subwavelength scale,the metasurface serves as a powerful tool for polarization
