自文明之初，控制光就令人类着迷，导致现代光学发展的几个世纪的研究仍然是灵感的源泉。超材料的出现--通过组装比波长小的组成元素而构建的具有非常规特性的人造材料--为操纵光传播开辟了新的途径。现在，来自密歇根大学安阿伯的Carl Pfeiffer和Anthony Grbic在《物理评论快报》上发表文章，报道了一种新的“超材料表面”的实验演示，这种新的“超材料表面”是一种基于超材料的薄屏幕，能够以任意方式重塑通过它传输的射频波，同时最大限度地减少不必要的反射[1]。
Controlling light has fascinated mankind since the dawn of civilization, and the centuries of studies leading to the development of modern optics can still be a great source of inspiration. The advent of metamaterials—artificial materials with unconventional properties built by assembling smaller-than-wavelength constituent elements—has opened new venues for the manipulation of light propagation. Now, writing in Physical Review Letters, Carl Pfeiffer and Anthony Grbic from the University of Michigan, Ann Arbor, report the experimental demonstration, inspired by a three-century-old optical principle, of a new “metasurface”: a metamaterial-based thin screen capable of reshaping, in arbitrary ways, a radio-frequency wave transmitted through it, while at the same time minimizing undesired reflections [1].
