Latest Negative index metamaterials Stories
DUBLIN, May 8, 2014 /PRNewswire/ -- Research and Markets (http://www.researchandmarkets.com/research/g35t2v/metamaterials)
The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers.
Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials – artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition.
In a vacuum, light moves extraordinarily fast. Fast enough to circle the Earth seven times before you can literally blink your eye. When light travels through matter, however, it slows down by just less than a factor of five.
Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.
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.
A new type of active metamaterial that incorporates semiconductor devices into conventional metamaterial structures is demonstrating an ability to have power gain while retaining its negative refraction property, a first in the world of metamaterials research.
Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires.
CFN scientists at KIT achieve optical invisibility in the visible light spectrum.
Cheaper, lighter and more energy-efficient broadband devices on communications satellites may be possible using metamaterials to modify horn antennas.
