摘要

采用全波数值模拟方法设计并分析了多层金属介质鱼网元结构的光学特性。我们报告负折射在红外光谱范围与低损耗。大多数先前的研究报告负折射在这个范围内使用堆叠渔网设计与金或银金属。我们的元结构是由铜/SiO2/铜堆叠渔网组成的，它是cmos兼容的，并且具有与使用贵金属的元结构相当的损失。

Towards CMOS-Compatible Negative-Index Metastructures

We design and analyze the optical properties of multilayered metal-dielectric fishnet metastructures using fullwave numerical simulations. We report negative refraction at the infrared spectral range with low loss. Most previous studies reported negative refraction in this range using stack fishnet design with either gold or silver metal. Our metastructure is made up of copper/SiO2/copper stack fishnet, which is CMOS-compatible and features losses comparable to those in metastructures utilizing noble metals.
