Zero-Index MetaMaterial Holds Promise For Future Quantum Networks And Light Sources
2013-12-06 08:25:49

Lawrence Berkeley National Laboratory The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. While quantum technologies remain grist for science fiction, a team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley...

Quest For ‘Invisibility Cloak’ Remains Elusive, It So Appears
2013-11-12 07:43:18

redOrbit Staff & Wire Reports - Your Universe Online Limitations in current cloaking technology allow objects to be temporarily concealed at only narrow wavelengths of light or microwaves, while many newer designs actually make things more visible, experts at the University of Texas acknowledged on Monday. Current cloaking devices, which are made of a variety of materials such as planes of glass, work by bending light around objects to make them temporarily invisible. Scientists...

An Ultra Secure Optical Communications Network With Temporal Cloaking
2013-06-06 10:07:26

redOrbit Staff & Wire Reports - Your Universe Online Researchers at Purdue University have demonstrated a temporal cloaking device for optical communications that bends light to create holes in time, something that could have important implications for sending secret messages over fiber optic cables or thwarting would-be eavesdroppers. "More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the...

Researchers Demonstrate Thermal Invisibility Cloak
2013-05-12 09:39:38

redOrbit Staff & Wire Reports — Your Universe Online A team of French and German researchers has designed and successfully tested a prototype “invisibility cloak” capable of hiding objects from heat, according to research published in Friday´s edition of Physical Review Letters. According to Timur Moon of the International Business Times, the device features a flat, five-centimeter wide area at its center, which was “impervious” to the heat that...

Invisibility Cloak For Thermal Flow Constructed By Researchers
2013-05-08 15:09:27

Karlsruhe Institute of Technology By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal. “For the thermal invisibility cloak, both materials...

Duke University Engineers Create Invisibility Cloak With 3D Printer
2013-05-06 15:11:00

Lee Rannals for redOrbit.com — Your Universe Online Duke University engineers are developing a way for you to create your own visibility cloak with a 3D printer. Three-dimensional printing is growing in popularity, and the cost for a MakerBot Replicator 2 is now just $2,199. Scientists are also working harder and harder to turn Harry Potter's invisibility cloak into a reality. A group wrote in the New Journal of Physics in March about how they developed a new cloak that is able...

Metascreen Makes Invisibility Cloaks A Potential Reality
2013-03-26 18:29:53

Lee Rannals for redOrbit.com — Your Universe Online Harry Potter had one, and maybe one day so will you, if the new invisibility cloak method described in the New Journal of Physics comes to fruition. US researchers have developed a new cloak that is just micrometers thick and is able to hide three-dimensional objects from microwaves in their natural environment, in all directions from all the observers' positions. Previously, scientists have developed invisibility cloaks that...

Researcher Improving On Invisibility Cloak Concepts
2012-11-12 12:57:49

Michael Harper for redOrbit.com — Your Universe Online The idea of an invisibility cloak is an attractive one to the human psyche. The ability to be present when we´re thought to be absent is a juicy prospect. Not only could we finally find out what people say about us behind our backs, but we´d also be able to watch people without being detected, as well as play some of the world´s greatest pranks. Now, in the latest attempt to turn science fiction into science...

Invisibility, once the subject of magic or legend, is slowly becoming reality. Over the past five years mathematicians and other scientists have been working on devices that enable invisibility cloaks — perhaps not yet concealing Harry Potter, but at least shielding small objects from detection by microwaves or sound waves. A University of Washington mathematician is part of an international team working to understand invisibility and extend its possible applications. The group has...

'Trapped Rainbow' Effect Demonstrated By Invisibility Cloak Array
2012-05-26 04:42:44

Researchers from the Towson University and University of Maryland announced on Friday that they had essentially trapped a rainbow, assembling an array consisting of over 25,000 miniature invisibility cloaks to slow light to a near halt. The invisibility cloak array, which lead author Dr. Vera Smolyaninova and colleagues describe in the latest edition of the Institute of Physics' and German Physical Society's New Journal of Physics, is the first device of its kind and is comprised of cloaks...
