项目摘要

The area of optical metamaterials - nanostructured composites with tailored optical properties - has experienced explosive growth over the past decade, fueled in part by rapid developments in fabrication, characterization, computational science and theory. Over the years, various metamaterials have been developed to enable several groundbreaking applications, such as superlens, electromagnetic cloaks, ideal optical couplers and optical black holes. In addition, they hold the promise to revolutionize beam steering, coupling of light between far- and near-field and many other photonics-related areas. Many of the unique aspects of light control realized in metamaterials originate from the possibility of achieving vanishingly small permittivity, materials which are often referred to as epsilon-near-zero (ENZ) metamaterials. Indeed, these materials form the inner layer of optical cloaks, enable efficient light transfer through subwavelength slits, and have been suggested as the foundation for metatronic circuitry. Therefore, the creation of ENZ materials and, more importantly, the understanding of their interaction with light inside complex optical structures, have become increasingly important for future multidisciplinary research for next-generation photonic materials. From the materials standpoint, ENZ response can be achieved either in vicinity of the plasma frequency in homogeneous systems whose optical response is dominated by free electrons or by combining distinct components with either positive or negative permittivity together in a single composite "meta-"material. Here we propose to perform a comprehensive study of light-matter interaction in complex ENZ material systems. The combined expertise of the international team will provide a unique opportunity to experimentally study the electromagnetic properties of complex ENZ-containing systems based upon both homogenous and composite materials, with ENZ frequencies spanning the visible to mid-IR frequency ranges and unified by common theoretical framework. Our joint unique experimental capabilities will allow us to delineate the universal physics associated with real ENZ materials and assess the practical benefits of these highly demanded media.

光学超材料领域-具有定制光学特性的纳米结构复合材料-在过去十年中经历了爆炸式增长，部分原因是制造，表征，计算科学和理论的快速发展。多年来，各种超材料已经被开发出来，以实现几个突破性的应用，如超透镜，电磁斗篷，理想的光耦合器和光学黑洞。此外，它们有望彻底改变光束转向，远场和近场之间的光耦合以及许多其他光子学相关领域。在超材料中实现的光控制的许多独特方面源于实现极小介电常数的可能性，这些材料通常被称为ε近零（ENZ）超材料。事实上，这些材料形成了光学斗篷的内层，使光能够通过亚波长狭缝进行有效传输，并被建议作为元电子电路的基础。因此，创建ENZ材料，更重要的是，了解它们与复杂光学结构内的光的相互作用，对于下一代光子材料的未来多学科研究变得越来越重要。从材料的角度来看，ENZ响应可以在其光学响应由自由电子主导的均匀系统中的等离子体频率附近实现，或者通过将具有正或负介电常数的不同组分组合在一起在单个复合“Meta”材料中实现。在这里，我们建议进行一个全面的研究，在复杂的ENZ材料系统中的光-物质相互作用。国际团队的综合专业知识将提供一个独特的机会，以实验研究基于均匀和复合材料的复杂含ENZ系统的电磁特性，ENZ频率跨越可见光到中红外频率范围，并通过共同的理论框架统一。我们的联合独特的实验能力将使我们能够描绘与真实的ENZ材料相关的普遍物理学，并评估这些高要求介质的实际好处。
