超材料是一种人工设计的材料/结构，具有自然界中没有的特殊电磁特性和/或其他物理特性。在电磁波传播方向上只有一层或几层周期性或非周期性排列的元胞结构的电磁超材料可称为超表面。超表面可以看作是超材料的二维表示，可以实现对入射电磁波的幅度、相位和偏振状态/方向的控制。根据超表面独特的电磁特性及其巨大的优势，可以开发出一系列基于超表面的新型平面器件和系统。这篇综述文章的目的是首先介绍基本的亚表面，它的意义，性质和应用原理。同时，分析了规则亚表面和新发展起来的可重构亚表面的主要研究进展，重点介绍了幅度调制、相位调制、偏振调制和多维调制的类型。最后分析了超曲面的研究意义、发展趋势和重要的工程实际应用。
Metamaterial is a kind of material/structure that is artificially designed and has exceptional electromagnetic properties and/or other physical properties, not found in nature. A class of electromagnetic metamaterial with only one or a few layers of periodic or aperiodic arranged cell structures in the direction of electromagnetic waves propagation can be referred to as a metasurface. Metasurface can be considered as a two-dimensional representation of metamaterial and can realize the controlling of the amplitude, phase, and polarization state/direction of the incident electromagnetic wave. According to the novel electromagnetic characteristics of metasurface and its big advantages, a series of new planar devices and systems based on metasurface can be developed. The goal of this review article is firstly to provide introductions for basic metasurface, its significance properties, and application principles. Meanwhile, the main research progresses of regular metasurfaces and the newly developed reconfigurable metasurfaces are analyzed, focusing on the types of amplitude modulation, phase modulation, polarization modulation, and multidimensional modulation. Finally, the research significances of metasurface development trend and important engineering practical applications are analyzed in the end.
