چکیده
The invention of metamaterials prompts reconsideration of a number of fundamental physical phenomena and enables a variety of unique properties and functionalities. These include negative refractive index, magnetism at optical frequencies, sub-wavelength resolution, “backward” phase matching conditions for nonlinear optical processes, and even rendering objects invisible – cloaking. In this brief review, recent progress in basic theory, design, fabrication, characterization, and potential applications of optical metamaterials is discussed.

Giant Goos-Häenchen Shift of a Gaussian Beam Reflected from One-Dimensional Photonic Crystals Containing Left-Handed Lossy Metamaterials
We perform a theoretical investigation on the Goos-Häenchen shift (the lateral shift) in one-dimensional photonic crystals (1DPCs) containing left-handed (LH) metamaterials. The effect was studied by use of a Gaussian beam. We show that the giant lateral displacement is due to the localization of the electromagnetic wave which can be both positive and negative depending on the incidence angle o...
متن کاملA Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
متن کاملGiant optical forces in planar dielectric photonic metamaterials.
We demonstrate that resonant optical forces generated within all-dielectric planar photonic metamaterials at near-infrared illumination wavelengths can be an order of magnitude larger than in corresponding plasmonic metamaterials, reaching levels many tens of times greater than the force resulting from radiation pressure. This is made possible by the dielectric structures' freedom from Joule lo...

We demonstrate the first addressable reconfigurable photonic metamaterials thus enabling control over optical material properties with simultaneous spatial and temporal resolution. Potential applications of random access metadevices include active focusing, beam steering, dynamic transformation optics and video holography.
متن کاملCrystalline metamaterials for topological properties at subwavelength scales
The exciting discovery of topological condensed matter systems has lately triggered a search for their photonic analogues, motivated by the possibility of robust backscattering-immune light transport. However, topological photonic phases have so far only been observed in photonic crystals and waveguide arrays, which are inherently physically wavelength scaled, hindering their application in com...
متن کاملConnected bulk negative index photonic metamaterials.
We show the designs of bulk one- and two-dimensionally isotropic photonic negative index metamaterials working around telecom wavelengths. The designed structures are inherently connected, which makes fabrication by direct laser writing and chemical vapor deposition or other techniques possible.
