Transformation optics: approaching broadband electromagnetic cloaking
An approach to broadband cloaking of light waves is analysed for a simplified case of a scaling transformation for a general cylindrical coordinate system. The proposed approach requires metamaterials with specifically engineered dispersion. The restriction on the signs of gradients in the dispersion dependencies of the dielectric permittivity and the magnetic permeability for different operati...
متن کاملCloaking a sensor via transformation optics.
Ideal transformation optics cloaking at positive frequency, besides rendering the cloaked region invisible to detection by scattering of incident waves, also shields the region from those same waves. In contrast, we demonstrate that approximate cloaking permits a strong coupling between the cloaked and uncloaked regions; careful choice of parameters allows this coupling to be amplified, leading...
متن کاملCloaking Devices, Electromagnetic Wormholes, and Transformation Optics
We describe recent theoretical and experimental progress on making objects invisible to detection by electromagnetic waves. Ideas for devices that would have once seemed fanciful may now be at least approximately implemented physically using a new class of artificially structured materials called metamaterials. Maxwell’s equations have transformation laws that allow for design of electromagneti...
متن کاملApplication of Transformation Optics for the Purpose of Cloaking
Transformation optics is an allied area comprising of differential geometry and electrodynamics [1]. The quest of humans to attain invisibility seems credible with the realisation of this field. The conceptualization of invisibility has been indicated in scientific parlance as cloaking which can be explained as bending the path of the ray around the body of interest in order to masquerade its p...
