论文摘要
完美的金属膜，周期性的切割缝隙，各向异性金属超材料膜模仿介电板，并在垂直于缝隙的方向上支持带导的电磁波。在这里，我们介绍了金属跨表面的超晶格，这些超晶格在一段时间内包括多个缝隙，并证明了超晶格支持连续体中的Fano共振和绑定状态。 FANO共振和绑定状态的数量取决于超级晶格期间的缝隙数。金属跨表面超晶格提供了操纵电磁波的新机制，从微波炉到远红外波长，可以将传统的金属视为完美的电导导体。
A perfect metal film with a periodic arrangement of cut-through slits, an anisotropic metallic metamaterial film, mimics a dielectric slab and supports guided electromagnetic waves in the direction perpendicular to the slits. Here, we introduce metallic metasurface superlattices that include multiple slits in a period, and demonstrate that the superlattices support the Fano resonances and bound states in the continuum. The number of Fano resonances and bound states depend on the number of slits in a period of superlattices. The metallic metasurface superlattices provide new mechanisms to manipulate electromagnetic waves, ranging from microwave to far-infrared wavelengths, where a conventional metal can be considered as a perfect electric conductor.
