Uber-fast computers operating 1,000 times the actual speed, 10 times more powerful magnifying microscopes, able to spy on the DNA directly, more efficient solar energy capturing devices, enhanced sensors or invisibility cloaks are only a few of the goals that the new optical science field promises to achieve. If prop... |

Scientists have built a device that, if applied to larger scales, would allow ocean waves, even those as big as a tsunami, to travel through a large structure (an offshore platform or even an island) without the waves or the respective structure being altered at all.Invisibility doesn't just refer to light and v... |

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... |

If it's light manipulation, then we're talking about metamaterials. Researchers report to have improved the design of T-ray sensors with the help of a metamaterial that guides T-ray light across the surface of the detector. T-ray sensors are thought to become the next generation of explosive and poison dete... |

It is humankind's never-dying dream, from the oldest myths to SF movies. Now, could the "electromagnetic wormhole" make us invisible? A team led by Allan Greenleaf of the University of Rochester has investigated a way to achieve this. The result would not be the classical wormhole, a theoretical bend in space an... |

One day Harry Potter's magic could be child's play and people could wear lightweight, magical cloaks, the result of high-performance from the latest technologies rendering them invisible. A Swedish/Chinese team led by Zhichao Ruan, Min Yan si Curtis W. Neff, has made a theoretical analysis of a column-shap... |

The invisibility is descending from fiction and movies to reality. New measurements show how to build an electromagnetic "wormhole", an invisible tube from both sides, that allows the light to pass down the unseen center. The idea is based on the technology of the spherical invisibility cloak proposed in 2006. An inv... |

The glass or plastic lenses in your eyeglasses redirect, or bend light into the right direction to focus it when your own eyes are no longer capable of doing so.When looking through a lens that is not fitted to your eye, the image looks distorted to a small angle, exactly like looking at a straw emerged half way in w... |
