中文摘要:
      超构表面作为二维形式的超构材料,在分界面处可以对透射、反射电磁波产生特定的相位分布,因此能够灵活调控电磁波前。超构表面的低剖面二维平面结构,在电磁调控领域具有广泛的应用前景,一系列的超构表面应用应运而生。主要介绍了超构表面的设计发展以及其应用,主要包括天线应用、RCS减缩、特殊波束、有源超构表面等4个方面。首先,在天线应用方面,超构表面可用于实现高增益透镜和极化转换功能;其次,从吸波型和散射调控型2种不同工作机理的角度介绍了应用于RCS减缩的超构表面;然后,针对特殊波束,主要介绍了超构表面在涡旋波束和全息成像中的应用;最后,从加载不同有源原件的角度分析有源超构表面的发展,并未来超构表面发展值得深入研究的方向。
英文摘要:
      Meta-surfaces regarded as the two dimensional types of meta materials can generate specific phase distributions to the transmissive and the reflective electromagnetic waves at the interface enabling to flexibly manipulate wave fronts. Due to their low profile and planar structures, the meta surfaces have wide potentials in the applications of electromagnetic manipulating, and a series of applications arise. This paper mainly introduces the design process of the meta surfaces and their applications in antennas, RCS reduction, special beams and active regions. Firstly, in the application of antennas, the meta surfaces can realize high gain lenses and the polarization converters. Then, the meta surfaces with different working principles of absorption and scattering controlling are adopted to reduce RCS. And also, the application of special beams mainly include the vortex beam transmission and the holographic imaging. Finally, the active meta-surfaces are introduced from the aspect of loading different active components. Moreover, this paper summaries the future directions of the meta-surface research.
