论文摘要
我们检查了分层的超材料结构，这些结构由Epsilon-Near-Zero（ENZ）和介电材料的交替膜组成，并表明，对于这种堆栈，可以增强ENZ的屈光，反射或吸收性。所提出的结构利用了几个接口，引导模式和等离子激发的共振来实现所需的增强，这不是有效的介质。我们使用分析建模工具来展示不同的自由度如何影响堆栈的性质，并为此类结构提出了实验可行的参数。
We examine layered metamaterial structures consisting of alternating films of epsilon-near-zero (ENZ) and dielectric material, and show that for such a stack it is possible to enhance the refractive, reflective or absorptive properties of the ENZ. The proposed structure takes advantage of resonances from several interfaces, guided modes, and plasmon excitations to achieve the desired enhancement, and it is not an effective medium. We use analytical modeling tools to show how the different degrees of freedom affect the properties of the stack, and propose experimentally feasible parameters for such structures.
