摘　　要：传统光学系统(如透镜、波片和全息片等)在光程远大于波长尺度的范围内实现对光波前的调控,其中振幅、相位和偏振的改变均依赖于光束反射、折射和衍射过程所累积的动态光程差。近年来涌现出的平面超薄光学系统因突破了传统设计的局限性而受到各个领域研究人员的青睐。本文着重介绍基于表面等离子激元的超表面在自由空间光场和局域光场波前调控方面的最新进展,阐述相关机理和具体应用,并结合国内外研究现状,分析现有技术存在的瓶颈且对该领域未来的发展趋势进行探讨和展望。Conventional optical systems （lenses, wave-plates and holograms） shape the wavefront of light within the range of an optical path that is much larger than the wavelength of light. The control of amplitude, phase and polar- ization of light depends on the dynamic optical path difference accumulated through the reflection, refraction and diffraction. Recently, planar ultrathin optical components have attracted tremendous attention by removing such tra- ditional limitations. In this paper, we mainly review the recent progress of plasmonic metasurfaces with respect to wavefront shaping of free space and localized optical fields, including the fundamental mechanisms and applications Both the drawbacks of existing technology and potential development are highlighted.
