论文摘要
由于它们对电磁场的空间分布的前所未有的控制，元信息引起了重大研究的兴趣。本文中，我们提出了跨表面镶嵌的概念，以实现可重构的散射功能。由相同结构组成的方形元瓷砖被安排为填充表面。瓷砖表面的电磁散射取决于元瓷砖的方向分布。我们提出了三个由二元元素组成的元瓷砖的典型案例，以实现几种不同的散射模式。这项研究提供了一种替代方法，可以构建无需外部刺激和复杂制造的可重构和多功能的跨表面设备。
Metasurfaces have attracted significant research interest owing to their unprecedented control over the spatial distributions of electromagnetic fields. Herein we propose the concept of metasurface tessellation to achieve reconfigurable scattering functions. Square meta-tiles, composed of identical structures, are arranged to fill a surface. The electromagnetic scattering of the tiled surface is determined by the orientation distribution of the meta-tiles. We present three typical cases of meta-tiles consisting of binary elements to realize several distinct scattering patterns. This study provides an alternative method to build reconfigurable and multi-functional metasurface devices without external stimuli and complicated fabrication.
