摘　　要：超构表面是人工设计的二维平面结构,可为光学器件的小型化和集成化提供新的思路。近年来,随着这一领域的不断发展,基于超构表面光学的各种光场调控机理和功能器件被提出。本文以光场操控的琼斯矩阵自由度为出发点,对近十年来的超构表面光学进展进行归类和综述,总结不同自由度琼斯矩阵的设计方法和相应的应用,并展望多自由度的超构器件研究的发展趋势。Significance As a layer of artificially designed two-dimensional planar structure,the metasurface provides a new platform for the miniaturization and integration of optical devices.In recent years,with the continuous development of this field,a variety of optical mechanisms and optical functional devices based on metasurfaces have been proposed.Despite their seemingly diverse functionalities,they can be all attributed to the control of different degrees of freedom in the Jones matrix.The Jones matrix is commonly employed to describe the ability of optical devices to control polarization,amplitude,and phase of light,with a maximum number of eight degrees of freedom.Especially,more controlled degrees of freedom lead to diverse functionalities that can be achieved.For example,a single degree of freedom in the Jones matrix can be adopted for anomalous transmission.By increasing to two degrees of freedom,such as independent control of amplitude and phase of a specific component of the Jones matrix,the integration of color printing and holography can be realized.From the perspectives of the degrees of freedom in the Jones matrix,we classify and summarize the designs and applications of metasurface research in recent years to help researchers better understand the physical mechanisms of different functionalities of metasurfaces.Progress Our study focuses on the designs and applications of metasurfaces from the perspectives of the degrees of freedom in the Jones matrix.We firstly argue that all the functionalities of metasurfaces can be categorized into different degrees of freedom in Jones matrix and the more controlled degrees of freedom lead to diverse functionalities that can be realized(Fig.1).Each component of the Jones matrix has two terms of amplitude and phase.Therefore,different mechanisms to control the phases including the geometry phase,resonance phase,and propagation phase are introduced to realize one degree of freedom(Fig.2),which can be utilized for functionalities of metalens,hologram,and anomalous tran
