Optical Negative-Index Metamaterials
REVIEW ARTICLE Optical negative-index metamaterials Artifi cially engineered metamaterials are now demonstrating unprecedented electromagnetic properties that cannot be obtained with naturally occurring materials. In particular, they provide a route to creating materials that possess a negative refractive index and offer exciting new prospects for manipulating light. This review describes the recent progress made in creating nanostructured metamaterials with a negative index at optical wavelengths, and discusses some of the devices that could result from these new materials. VLADIMIR M. SHALAEV designed and placed at desired locations to achieve new functionality. One of the most exciting opportunities for metamaterials is the School of Electrical and Computer Engineering and Birck Nanotechnology development of negative-index materials (NIMs). Th ese NIMs bring Center, Purdue University, West Lafayette, Indiana 47907, USA. the concept of refractive index into a new domain of exploration and e-mail: [email protected] thus promise to create entirely new prospects for manipulating light, with revolutionary impacts on present-day optical technologies. Light is the ultimate means of sending information to and from Th e arrival of NIMs provides a rather unique opportunity for the interior structure of materials — it packages data in a signal researchers to reconsider and possibly even revise the interpretation of zero mass and unmatched speed. However, light is, in a sense, of very basic laws. Th e notion of a negative refractive index is one ‘one-handed’ when interacting with atoms of conventional such case. Th is is because the index of refraction enters into the basic materials. Th is is because from the two fi eld components of light formulae for optics. -
Phase Reversal Diffraction in Incoherent Light
Phase Reversal Diffraction in incoherent light Su-Heng Zhang1, Shu Gan1, De-Zhong Cao2, Jun Xiong1, Xiangdong Zhang1 and Kaige Wang1∗ 1.Department of Physics, Applied Optics Beijing Area Major Laboratory, Beijing Normal University, Beijing 100875, China 2.Department of Physics, Yantai University, Yantai 264005, China Abstract Phase reversal occurs in the propagation of an electromagnetic wave in a negatively refracting medium or a phase-conjugate interface. Here we report the experimental observation of phase reversal diffraction without the above devices. Our experimental results and theoretical analysis demonstrate that phase reversal diffraction can be formed through the first-order field correlation of chaotic light. The experimental realization is similar to phase reversal behavior in negatively refracting media. PACS numbers: 42.87.Bg, 42.30.Rx, 42.30.Wb arXiv:0908.1522v1 [quant-ph] 11 Aug 2009 ∗ Corresponding author: [email protected] 1 Diffraction changes the wavefront of a travelling wave. A lens is a key device that can modify the wavefront and perform imaging. The complete recovery of the wavefront is possible if its phase evolves backward in time in which case an object can be imaged to give an exact copy. A phase-conjugate mirror formed by a four-wave mixing process is able to generate the conjugate wave with respect to an incident wave and thus achieve lensless imaging[1]. A slab of negative refractive-index material can play a role similar to a lens in performing imaging[2, 3, 4, 5, 6, 7]. Pendry in a recent paper[8] explored the similarity between a phase-conjugate interface and negative refraction, and pointed out their intimate link to time reversal. -

EEE17 Negative Refraction in Metamaterials
EEE 17 Negative Refraction in Metamaterials EEE17 Negative Refraction in Metamaterials Cheng Zixiang Raffles Institution Lian Kay Sean Temasek JC NRP Supervisor: Prof. Luo Yu NTU EEE 17 Negative Refraction in Metamaterials Research Plan Artificially engineered metamaterials have unique properties that cannot be obtained with natural materials. Negative Index Metamaterials or NIMs, as they are commonly known, have a negative refractive index, thus light rays are refracted on the same side of the normal on entering the material. Our project focuses on two ways of achieving NIMs. One would be constructing dielectric metamaterials created with a periodic array of subwavelength unit cells, the other would be creating a hyperbolic metamaterial by alternating layers of mediums of different refractive index. The aim of our project is to investigate the materials that can be used to construct the hyperbolic and dielectric method of realising negative refraction and the efficacy of the material used. Both approaches achieved negative refraction in the mid infra-red frequency. The simulation would be done with COMSOL software. EEE 17 Negative Refraction in Metamaterials Abstract A metamaterial is a material engineered to have a property not found in nature. Metamaterials usually gain their properties from structure rather than composition, offering a great freedom in material design. Recently, well designed metamaterials have received much interest because their atypical interaction with electromagnetic waves that can be used for subwavelength imaging and designing cloaking devices. In my project, that property is to be able to realise negative refraction in certain frequencies of the electromagnetic spectrum. The metamaterial concept was proposed in 1999 by John Pendry, who detailed in a paper in 2000 applying the concept of negative refraction to create a lens that can focus light onto a sub-wavelength area. -
Negative Refraction at Deep-Ultraviolet Frequency in Monocrystalline Graphite
Negative refraction at deep-ultraviolet frequency in monocrystalline graphite Jingbo Sun, Ji Zhou*, Lei Kang, Rui Wang, Xianguo Meng, Bo Li, Feiyu Kang and Longtu Li State Kay Lab of New Ceramics and Fine Processing, Department of Materials Science and Engineering, Tsinghua University, Beijing 100084, China Abstract: Negative refraction is such a prominent electromagnetic phenomenon that most researchers believe it can only occur in artificially engineered metamaterials. In this article, we report negative refraction for all incident angles for the first time in a naturally existing material. Using ellipsometry measurement of the equifrequency contour in the deep-ultraviolet frequency region (typically 254 nm), obvious negative refraction was demonstrated in monocrystalline graphite for incident angles ranging from 20o to 70o. This negative refraction is attributed to extremely strong anisotropy in the crystal structure of graphite, which gives the crystal indefinite permeability. This result not only explores a new route to identifying natural negative-index materials, but it also holds promise for the development of an ultraviolet hyperlens, which may lead to a breakthrough in nanolithography, the most critical technology necessary for the next generation of electronics. Since the concept of negative-index materials (NIMs) was first proposed by Veselago1, it has been realised by various mechanisms such as left-handed materials2-4, photonic crystals5, 6, and artificially indefinite media7, 8. A well-established route for constructing NIM structures is based on Veselago’s theory of left-handed materials (LHM), simultaneous negative permittivity (ε), and magnetic permeability (μ) with different types of metamaterials9−12. Recent experimental13 and theoretical14 results have also shown negative refraction phenomena in photonic crystals in regimes of negative group velocity and negative effective index above the first band near the Brillouin zone centre (Γ), without the requirement of an overlap in negative permittivity and permeability. -
