摘　　要：超表面是一种基于广义斯涅尔定律,通过控制波前相位、振幅以及偏振进行电磁/光学波束调控的新结构,其新颖的机制和灵活的结构设计展现出广阔的应用前景。本文阐明了超表面调控波束的物理机理,叙述超表面的发展历程,即从实现超表面到提高有效分量和动态可调超表面的研究过程,总结了超表面透镜、超表面偏振器、表面等离子体激元调控等功能器件,并对超表面有待解决的问题以及今后的发展趋势进行了探讨。Metasurface is a new ultrathin components which based on generalized Snell＇s Law to manipulate electromagnetic（ EM） and light beam in the phase,amplitude and polarization. It shows broad application prospects due to its novel mechanism and flexible design. This review focuses on the physical mechanism of metasurface-control beams and the development of metasurface including the original metasurface,the method to increase anomalous coefficient of reflection and transmission,and tunable metasurface components. Subsequently,this review introduces ultrathin flat lenses,metasurface polarizer,unidirectional excitation of surface plasmon polariton and others metasurface devices. At last,challenges and prospectives on metasurface are also discussed.
