How to hide a dimension from view Compacted dimensions are essential ingredients of advanced string theories; the extra dimensions used to describe the world are hidden from view, or compacted. Pendry et al. used concepts of transformation optics, in which metamaterials are designed to produce specific optical properties, to show theoretically that compacted dimensions could be possible in plasmonic structures. For example, simulations with a metallic grating and periodically doped graphene revealed that two-dimensional structures exhibit optical properties of a bulk material. To all intents and purposes, it looks as if one of the dimensions is compacted. The results could have practical application in designing broadband optical absorbers. Science, this issue p. 915 Plasmonic excitations of a transformed grating may serve as a model for compacted dimensions. In advanced field theories, there can be more than four dimensions to space, the excess dimensions described as compacted and unobservable on everyday length scales. We report a simple model, unconnected to field theory, for a compacted dimension realized in a metallic metasurface periodically structured in the form of a grating comprising a series of singularities. An extra dimension of the grating is hidden, and the surface plasmon excitations, though localized at the surface, are characterized by three wave vectors rather than the two of typical two-dimensional metal grating. We propose an experimental realization in a doped graphene layer.

压缩尺寸和奇异等离子体表面

如何从视图中隐藏维度 压缩维度是高级弦理论的基本要素;用于描述世界的额外维度被隐藏或压缩。彭德里等人。使用变换光学的概念,其中超材料被设计为产生特定的光学特性,从理论上表明在等离子体结构中压缩尺寸是可能的。例如,使用金属光栅和周期性掺杂石墨烯的模拟表明二维结构表现出块状材料的光学特性。从所有意图和目的来看,似乎其中一个维度被压缩了。结果可以在设计宽带光吸收体方面具有实际应用。科学,这个问题 p。915 变换光栅的等离子体激发可以作为压缩尺寸的模型。在先进的场论中,空间可以有四个以上的维度,多余的维度被描述为在日常长度尺度上是压缩的和不可观察的。我们报告了一个与场论无关的简单模型,用于在以光栅形式周期性构造的金属超表面中实现的压缩维度,该表面包含一系列奇点。光栅的额外维度是隐藏的,表面等离子体激发虽然位于表面,但其特征是三个波矢量,而不是典型二维金属光栅的两个波矢量。我们提出了在掺杂石墨烯层中的实验实现。在日常长度尺度上被描述为压缩和无法观察到的多余尺寸。我们报告了一个与场论无关的简单模型,用于在以光栅形式周期性构造的金属超表面中实现的压缩维度,该表面包含一系列奇点。光栅的额外维度是隐藏的,表面等离子体激发虽然位于表面,但其特征是三个波矢量,而不是典型二维金属光栅的两个波矢量。我们提出了在掺杂石墨烯层中的实验实现。在日常长度尺度上被描述为压缩和无法观察到的多余尺寸。我们报告了一个与场论无关的简单模型,用于在以光栅形式周期性构造的金属超表面中实现的压缩维度,该表面包含一系列奇点。光栅的额外维度是隐藏的,表面等离子体激发虽然位于表面,但其特征是三个波矢量,而不是典型二维金属光栅的两个波矢量。我们提出了在掺杂石墨烯层中的实验实现。光栅的额外维度是隐藏的,表面等离子体激发虽然位于表面,但其特征是三个波矢量,而不是典型二维金属光栅的两个波矢量。我们提出了在掺杂石墨烯层中的实验实现。光栅的一个额外维度是隐藏的,表面等离子体激发虽然位于表面,但其特征是三个波矢量,而不是典型二维金属光栅的两个波矢量。我们提出了在掺杂石墨烯层中的实验实现。
