Mathematicians have developed the theory for a Harry Potter style 'cloaking' device which could protect buildings from earthquakes. Scientists have been working on the theory of invisibility cloaks which, until recently, have been merely the subject of science fiction. In recent times, however, scientists have been getting close to achieving 'cloaking' in a variety of contexts. The new work focuses on the theory of cloaking devices which could eventually help to protect buildings and structures from vibrations and natural disasters such as earthquakes.

Physicists in Germany are refining the structure of an invisibility cloak to such an extent that it is also effective in the visible spectral range. The minute invisibility cloak is smaller than the diameter of a human hair. It makes the curvature of a metal mirror appear flat, as a result of which an object hidden underneath becomes invisible

(Helmholtz Association of German Research Centres) Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object appears to be non-existent.

Researchers have created a new kind of cloaking material that can render objects invisible in the terahertz range. Though this design can't translate into an invisibility cloak for the visible spectrum, it could have implications in diagnostics, security, and communication.

For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans. The new device is a leap forward in cloaking materials.

Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality.

Though this design can't translate into an invisibility cloak for the visible spectrum, it could have implications in diagnostics, security, and communication.
