A paper published in the January 25 issue of the New Journal of Physics describes a tube-like structure that is capable of masking three-dimensional objects from microwave light. This invisibility cloak is one of the few out there that is capable of hiding 3D objects from view.
The tube itself is made up of insulat... |

A collaboration of physicists at the Cornell University, in Ithaca, New York, announces the creation of a hole in time, an artificial construct that enables users to conceal the very existence of a light pulse for about 110 nanoseconds. This is one of the most remarkable scientific discoveries made in 2011.

Experts with the Imperial College London (ICL) announce the creation of the world's first invisibility cloak for magnetic field. What the antimagnet shield does is shield a target object from the effects of the magnetic field for as long as researchers want it to.According to the research team, which is based in... |

Science-fiction is indeed starting to become reality, like many predicted years ago. Recently, scientists developed an invisibility cloak of sorts, that works for sounds emitted underwater. The finding is important, as it could be used to make submarines completely “invisible” to enemy sonars. The new aco... |

Researchers from the University of Illinois at Urbana Champaign (UI) have managed to create a new type of metamaterial that is able to guide sound waves through very tiny structures. The innovation could have significant applications in the field of medicine, as well as for new military devices. Doctors could use it ... |

The new metamaterial developed at Duke University and Boston College presents tiny geometric features that are able to absorb both the electric and the magnetic components of electromagnetic radiation, in specific frequencies of the microwave spectrum. "Three things can happen to light when it hits a material. It ca... |

All previous invisibility cloak projects claimed at some point in time that a three-dimensional optical light cloak can be built. I won't deny that this is true, although I haven't bumped into any invisible objects lately which leads me to believe that this attempt has failed. Now, a new three-dimensional o... |

Invisibility cloaks and ultra-fast computers could one day be powered by such an exotic device, however, multiple problems need to be solved before these crystals become useful. Several metamaterials have been designed over the years, but the technological process involved in building them presents multiple technolog... |
