TLDR
The METATOY as discussed by the authors is a wave-optical component that trades in the continuity of the phase fronts and the precision to which they change light-ray elds in return forAbout:

Local light-ray rotation
TL;DR: In this article, a sheet structure consisting of two parallel Dove-prism sheets, each of which flips one component of the local direction of transmitted light rays around the sheet normal is presented.
Journal ArticleDOI
Dr TIM: Ray-tracer TIM, with additional specialist scientific capabilities
TL;DR: Simulation of the external appearance of Eaton lenses, Luneburg lenses and generalised focusing gradient-index lens (GGRIN) lenses, raytracing through interfaces between spaces with different optical metrics; and refraction with generalised confocal lenslet arrays, which are particularly versatile METATOYs.
Journal ArticleDOI
Perfect imaging with planar interfaces.
TL;DR: The most general homogenous, planar, light-ray-direction-changing sheet that performs one-to-one imaging between object space and image space is described and can be realized with generalized confocal lenslet arrays.

Experimental demonstration of a light-ray-direction-flipping METATOY based on confocal lenticular arrays
Michael Blair,Leo Clark,E. Alasdair Houston,G. D. Smith,Jonathan Leach,Alasdair C. Hamilton,Johannes Courtial +6 more
TL;DR: In this paper, it was shown that a sheet formed by two confocal lenticular arrays can flip one component of the local light-ray direction in a way that cannot be performed perfectly wave-optically.

Large-scale, white-light, transformation optics using integral imaging
Stephen Oxburgh,Chris D. White,Georgios Antoniou,Ejovbokoghene Orife,Tim Sharpe,Johannes Courtial +5 more
TL;DR: In this paper, a generalised confocal lenslet array is proposed to realize transformation-optical devices from structures of micro-structured sheets called generalized confocal lenseslet arrays.

Negative Refraction Makes a Perfect Lens
TL;DR: The authors' simulations show that a version of the lens operating at the frequency of visible light can be realized in the form of a thin slab of silver, which resolves objects only a few nanometers across.
Journal ArticleDOI
Metamaterials and negative refractive index.
TL;DR: Recent advances in metamaterials research are described and the potential that these materials may hold for realizing new and seemingly exotic electromagnetic phenomena is discussed.

Metamaterials for light rays: ray optics without wave-optical analog in the ray-optics limit
TL;DR: In this paper, the wave-optical analog of such transformations was studied in the ray-optics and scalar-wave limits, and it was shown that such an analog does not always exist.
