摘要:

我们检查分层的超材料结构组成的ε近零(ENZ)和介电材料的交替膜,并表明,对于这样的堆栈,它是可能的,以提高ENZ的折射,反射或吸收性能。所提出的结构利用来自几个界面、导模和等离子体激元激发的共振来实现所需的增强,并且它不是有效的介质。我们使用分析建模工具来显示不同的自由度如何影响堆栈的属性,并提出实验可行的参数,这样的结构。

英文摘要:

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.
