How metamaterials bend the paths of electromagnetic radiation (i.e. refraction) drives their peculiar applications. For example, a metamaterial invisibility cloak would bend the paths of light waves ...

Metamaterials are designed to have unique ... Examples include super-lenses to view objects at the molecular scale; invisibility cloaks, which refract all visible light; and perfect wave ...

Based on the linear transformation optics and the constitution theory of omnidirectionally matched transparent metamaterials ... omnidirectional invisibility cloak capable of concealing large ...

Physicists from Duke University unveil the world's first-ever invisibility cloak. (Thanks, J.K. Rowling!) The elaborate set-up was created using metamaterials, which are capable of manipulating ...

An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

It suggests that the invisibility cloaks that have captured much of the general interest in the field of optical metamaterials are just one manifestation of a more general topic, which the ...

Specific topics include sub-wavelength waveguiding and focusing, super-resolution imaging and nano-lithography beyond the diffraction limit of the light, negative refraction, and invisibility cloaking ...

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is ...

We envision a world in which the sort of invisibility cloaks, the kind that appear in Harry Potter books and movies, could soon be reality. We’d be able to disappear just like that. A number of ...
