Recently, two rich and exciting research fields, layered two-dimensional (2D) materials and metamaterials, have started overlapping. Metamaterials are artificial, engineered materials with broad metaphotonic prospects such as negative refraction, perfect lensing, subwavelength imaging, and cloaking. The possibility of achieving metaphotonic properties using metamaterials based on layered 2D materials has been extensively exploited. Because they are highly tunable and adjustable with the ease of micro- and nanofabrication, 2D materials exhibit diverse optical properties such as natural negative refraction, natural anisotropic behavior, and even hyperbolic dispersion. A combination of 2D materials with conventional metamaterials promises a variety of prospective applications. In this review, we illustrate how the concept of metamaterials and their associated metaphotonic capabilities are naturally born in 2D materials. The multifunctionality of 2D materials may enable the manufacture of novel optical devices that work in a broad frequency range, from visible to terahertz, with particularly low loss, high speed, gated tunability, and miniaturized sizes. This new area of research links the fields of photonics, optoelectronics, and plasmonics with that of metamaterials and may provide insights to future innovations for 2D-material-inspired metaphotonic devices.

自然产生于二维的人工超光子学。

最近，分层的二维（2D）材料和超材料已成为两个令人激动的令人兴奋的研究领域，它们相互重叠。超材料是具有广泛的超光子前景的人工，工程材料，例如负折射，完美的透镜，亚波长成像和隐身。使用基于分层2D材料的超材料来实现超光子特性的可能性已得到广泛利用。由于2D材料具有高度的可调谐性和可调整性，并且易于进行微细加工和纳米加工，因此它们具有多种光学特性，例如自然的负折射，自然的各向异性以及甚至双曲线的色散。2D材料与常规超材料的结合有望实现各种预期的应用。在这篇评论中我们说明了超材料的概念及其相关的超光子能力是如何自然地在2D材料中诞生的。2D材料的多功能性可以制造出新颖的光学器件，该器件可以在从可见光到太赫兹的宽频率范围内工作，并且损耗特别低，具有高速，门控可调性和小型化的特点。这一新的研究领域将光子学，光电子学和等离子学领域与超材料领域联系起来，并可能为启发2D材料启发的超光子器件的未来创新提供见识。门控的可调性和小型化。这一新的研究领域将光子学，光电子学和等离子学领域与超材料领域联系起来，并可能为启发2D材料启发的超光子器件的未来创新提供见识。门控的可调性和小型化。这一新的研究领域将光子学，光电子学和等离子学领域与超材料领域联系起来，并可能为启发2D材料启发的超光子器件的未来创新提供见识。
