【摘要】 将光波偏折到预定的非镜面折/反射方向是超构表面的一项重要能力，也是超构表面对光波进行复杂操控的基础。为了提高异常偏折超构表面的性能并拓展其应用，现有研究主要围绕设计理念、器件构型、演示应用等方面展开。目前光学超构表面的异常折射和反射效率已经提升至90%和99%，各种基于超构表面异常偏折光波调控的演示性应用也相继被提出。从物理机制、实现方法以及应用研究几方面出发，本文对光学超构表面异常偏折研究进行了回顾和讨论，同时也对潜在的挑战进行了总结，对异常偏折超构表面的进一步研究进行了展望。更多还原

【Abstract】 Deflecting light waves in a predetermined direction of non-specular refraction/reflection is an important property of metasurfaces and is also the basis for the manipulation of light waves by optical metasurfaces. To improve the performance of anomalous deflection metasurfaces and expand their applications,the existing research mainly focuses on the design methodology,configuration,and the demonstration of applications. At present,the anomalous refraction and reflection efficiencies of optical metasurfaces have been increased to more than 90% and 99%,respectively. Furthermore,various applications based on anomalous deflection have been proposed. Studies on anomalous deflection metasurfaces are reviewed and discussed from the aspects of physical mechanism,implementation method,and application. The potential challenges are also summarized and further studies of anomalous deflection metasurfaces are explored.更多还原
