标题： Low loss metasurfaces based on quantized meta-atom

摘要： 超表面已被提出作为一种新的范式来操控光并增强光与物质的相互作用。 传统的超表面受到材料损耗的限制，限制了其性能上限。 在这里，通过量化超原子，金属超表面的损耗被降低到介质超表面的水平，并提出了一种耦合模型来解释损耗的减少。 理论结果与有限元方法的仿真结果高度一致。 这种现象也在介质和二次量化超原子超表面中得到了再现。 有理由相信，这在共振领域是全新的，这项工作将为超表面的设计和应用带来新的启示。 它还将为超越超表面的其他共振领域提供理论支持。 显示英文摘要

摘要： Metasurfaces have been proposed as a new paradigm to manipulate light and improve light-matter interactions. Conventional metasurfaces are restricted to the loss of materials, limiting their performance ceiling. Here, the loss of metallic metasurfaces is reduced to the level of dielectric metasurfaces by quantizing the meta-atom, and a coupling model is proposed to interpret the loss reduction. The theoretical results are in excellent agreement with the finite-element method simulation results. This phenomenon is also reproduced in dielectric and second-quantized meta-atom metasurfaces. There is reason to believe that this is something new in the resonance field, and this work will shed new light on the designs and applications of metasurfaces. It will also pave theory support to other resonance fields beyond metasurfaces.
