Invisibility cloaks moved out of the realm of science fiction, and into reality, several years ago, but scientists are still having problems covering some regions of the electromagnetic spectrum. Now, a team of experts says that optical cloaks could be based on nanoscale silicon spheres. The same materials have bee... |

Scientist Mohammad-Reza Alam predicts that it may be possible to create an invisibility cloak capable of concealing ships, oil platforms, and other man-made structures, from the fury of rough seas. This is the first time such a technique has been proposed.
Creating such a scenario is entirely different from using m... |

An international research team managed to develop an inexpensive, simple system of camouflaging objects as if they were covered with an invisibility cloak. Generally, this cannot be done for macroscopic objects and in visible light, but the collaboration managed to circumvent the limitation.Taking inspiration from sc... |

Over the past few years, materials scientists have developed a series of new inventions, metamaterials that have exquisite physical and chemical properties. But because they are extremely advanced, they are still incredibly difficult to produce.A team of investigators from the Interuniversity Microelectronics Center ... |

Metamaterials are a very special class of materials that are engineered specifically for a certain job. Though they are basically common chemical elements, or mixes thereof, their internal structures are arranged differently than they are in nature. As such, metamaterials can be used for a variety of applications for... |

For many years, science-fiction and fantasy writers have been inspired by the idea of making something or someone disappear from view. Be it a cloak, a potion, a spell or a ring, plot lines always feature a device that can render things invisible, hiding them from danger, or allowing them to slip by unnoticed. But, f... |

Not two years ago, researchers managed to create the first 2D “invisibility cloak,” a material that was capable of concealing an object viewed from a fixed location by an observer. This was accomplished by manipulating the light hitting that object in such a manner that the photons were routed around it, ... |

With the inevitable advent of metamaterials and invisibility cloaks, the world is eager to know precisely how a hidden object would look like in real life. While practical applications are still some time away, German researchers at the Karlsruhe Institute of Technology have recently released a series of pictures on ... |

Scientists and engineers at the Imperial College London (ICL), in the United Kingdom, were recently awarded a new, £4.9-million ($8.1-million) grant to investigate the properties of metamaterials. The money, which came from The Leverhulme Trust, are destined for the creation of invisibility cloaks and perf... |

Many people believe that things such as teleportation, invisibility cloaks and time travel pertain only to science-fiction movies and books, but renowned theoretical physicist Dr. Michio Kaku believes that they may be a lot closer than we think. The expert, who collaborated in creating the string theory, reveals that... |

Scientists at the University of Utah have recently announced the development of a new mathematical model, which could lead to the creation of a novel cloaking method. The research is not aimed at producing “invisibility cloaks” that absorb visible light, but rather at creating new means of making stealth ... |

Physicists at the Boston College have recently managed to use new metamaterials to successfully control a beam of light employing a set of complex instructions. The achievement could have significant applications in the field of bending light around corners or other objects, and could contribute significantly to prod... |

Earthquakes are among the most brutal manifestations of nature, alongside volcano eruptions and tsunamis, and, as if that wasn't enough, oftentimes the three come together. Tremors strike in two ways – via body waves, which travel underground away from the initial point, and surface waves. The latter trave... |
