Dark solitons at nonlinear interfaces [PDF]
, 2010 The refraction of dark solitons at a planar boundary separating two defocusing Kerr media is simulated and analyzed, for the first time (to our knowledge). Analysis is based on the nonlinear Helmholtz equation and is thus valid for any angle of incidence.

Negative refraction makes a perfect lens
Physical Review Letters, 2000 With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those ...

Negative index of refraction in optical metamaterials. [PDF]
Optics Letters, 2005 A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range. Such behavior results from the plasmon resonance in the pairs of nanorods for both the electric and the magnetic components of ...

A method for creating materials with a desired refraction coefficient [PDF]
, 2009 It is proposed to create materials with a desired refraction coefficient in a bounded domain $D\subset \R^3$ by embedding many small balls with constant refraction coefficients into a given material. The number of small balls per unit volume around every

All-angle negative refraction of highly squeezed plasmon and phonon polaritons in graphene–boron nitride heterostructures [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2016 Significance Realizing negative refraction of highly squeezed polaritons is an important step toward the active manipulation of light at the extreme nanoscale.

Negative Refraction and Left-handed electromagnetism in Microwave Photonic Crystals [PDF]
, 2004 We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical ...

Amphoteric refraction at the interface between isotropic and anisotropic media [PDF]
, 2006 It is found that the amphoteric refraction, i.e. the refraction can be either positive or negative depending on the incident angles, could occur at a planar interface associated with a uniaxially anisotropic positive index media (PIM) or an anisotropic ...

Observation of negative refraction of Dirac fermions in graphene [PDF]
Nature Physics, 2015 Negative refraction has now been observed for Dirac fermions in graphene, and is used to create an electronic Veselago lens. Half a century ago, Veselago1 proposed ‘left-handed’ materials with negative permittivity and permeability, in which waves ...

What are the left-handed media and what is interesting about them? [PDF]
, 2004 We review the intensively discussed ideas about wave propagation and refraction in media where both electric permittivity and magnetic permeability are negative. The criticism against negative refraction as violating the causality principle is considered.
