【摘要】：超构表面是一种基于亚波长结构的功能膜层器件,也称超表面或二维超构材料。超构表面可在平面化的亚波长结构内产生异常的相位突变,从而为包括大口径平面成像、电磁虚拟赋形、大视场全息显示等应用提供有效手段。与传统的光学器件相比,超构表面器件具有亚波长尺度相位、振幅、偏振任意调控,轻薄、易集成、低损耗、表面可共形设计等诸多优点,因而受到广泛关注。本文对超构表面的相位调控原理进行分析,并据此对现有的超构表面进行分类,同时介绍了各类超构表面器件的特点和应用,最后对超构表面领域面临的挑战及有待进一步拓展的方向进行展望。
[Abstract]:Superstructure surface is a kind of functional film device based on subwavelength structure, which is also called supersurface or two-dimensional superstructure material. The superstructure surface can produce abnormal phase changes in the plane subwavelength structure, which provides an effective means for the applications including large aperture plane imaging, electromagnetic virtual shaping, large field holographic display and so on. Compared with traditional optical devices, superstructure surface devices have many advantages, such as sub-wavelength phase, amplitude, arbitrary control of polarization, lightweight, easy to integrate, low loss, conformal surface design and so on. In this paper, the phase control principle of the superstructure surface is analyzed, and the existing superstructure surface is classified according to this principle. The characteristics and applications of various kinds of superstructure surface devices are also introduced. Finally, the challenges in the field of superstructure surface and the direction to be further developed are prospected.
