generalized transformation optics of linear materials Cutting

We continue the development of a manifestly four-dimensional, completely covariant, approach to transformation optics in linear dielectric materials begun in a previous paper. This approach, which generalizes the Plebanski based approach, is systematically applicable for all transformations and all general linear materials. Importantly, it enables useful applications such as arbitrary relative generalized transformation optics of linear materials Cutting[1006.3364] Generalized Transformation Optics of Linear generalized transformation optics of linear materials CuttingJun 17, 2010 · Abstract: We continue the development of a manifestly 4-dimensional, completely covariant, approach to transformation optics in linear dielectric materials begun in a previous paper.

Cummer, Jörg Frauendiener, Jörg FrauendienerPublish Year: 2010Which is a new era of metamaterial physics?A new era of metamaterial physics is associated with all-dielectric meta-optics, which employs electric and magnetic Mie resonances of subwavelength particles with high refractive index for an optically induced magnetic response, thus underpinning a new approach to design and fabricate functional and practical metadevices.See all results for this question

The mathematical technique that enables us to design such artificial materials is called transformation optics 1, 2.See all results for this questionWhat are the effects of metamaterials in transformation optics?1. With the aid of metamaterials, the appeal of transformation optics goes beyond invisibility: it can create fascinating effects such as electromagnetic wormholes 53, hidden gateways 54, 55 and 'optical black holes' 56, 57, 58, 59.See all results for this questionTransformation optics in nonvacuum initial dielectric generalized transformation optics of linear materials CuttingNov 15, 2010 · Previous formulations of transformation optics have generally been restricted to transformations from relatively simple initial media, such as the vacuum, because of limitations due to their noncovariance. I show that a completely covariant approach enables arbitrary transformations from arbitrarily complex initial linear dielectrics.

Transformation optics is a mathematical method that is based on the geometric interpretation of Maxwells equations. This technique enables a direct link between a desired electromagnetic (EM) phenomenon and the material response required for its occurrence, providing a powerful and intuitive design tool for the control of EM fields on all length scales.Transformation optics and metamaterials | Nature MaterialsApr 23, 2010 · Transformation optics describes the capability to design the path of light waves almost at will through the use of metamaterials that control effective materials properties on Transformation Optics: From Classic Theory and generalized transformation optics of linear materials CuttingHis research interests are primarily concerned with transformation optics, sub-wavelength imaging and metamaterials. Yichao Liu is a member of Meta group of COER (Centre for Optical and Electromagnetic Research). He received his PhD from Zhejiang University in 2016 for his research on transformation optics and meta materials.

In this paper, transformation optics is presented together with a generalization of invisibility cloaking: instead of an empty region of space, an inhomogeneous structure is transformed via Pendry's map in order to give, to any object hidden in the central hole of the cloak, a completely arbitrary appearance.

A critical cut-off number for the refractive index may exist to excite such mode in the material. The results can be interesting particularly for materials with high refractive index as well as for anisotropic space-time metric formulations in Transformation Optics. 2016 Some results are removed in response to a notice of local law requirement.

Jan 01, 2016 · Lorentz space-time transformation has been applied to the phase factor of a plane electromagnetic wave in linear material medium. The derivation shows in the limiting case for v = c, the phase velocity converges to its monochromatic value implying no such dispersion effect can exist in free space. However in linear material medium, wave speed may exceed the monochromatic phase On spacetime transformation optics: temporal and Generalized transformation optics of linear materials Robert T Thompson, Steven A Cummer and Jörg Frauendiener Anisotropic singularities in chiral modified gravity Yannick Herfray, Kirill Krasnov and Yuri Shtanov Black hole nonmodal linear stability: the Schwarzschild (A)dS cases Gustavo Dotti Electromagnetic fields with vanishing scalar generalized transformation optics of linear materials CuttingOSA | Linear optical transformation with quasi-angle generalized transformation optics of linear materials CuttingA scheme of linear optical transformation based on quasi-angle states and quasi-orbital angular momentum states has been demonstrated with two spacial light modulators, a pinhole and a lens. In experiments, the generalized Pauli clock and shift matrix as well as the discrete Fourier transform matrix have been achieve with dimensionality of 7.

Aug 26, 2019 · Here, we utilize complex transformation optics (CTO) to derive generalized Veselago-Pendry (GVP) lenses without requiring a multivalued transformation. Unlike the conventional VP lens, the proposed lenses can fully recover the evanescent spectra under more general conditions that include the presence of (anisotropic) material loss/gain.Journal of Optics (United Kingdom) | [email protected]2012.
