A butterfly's wings and a peacock's feathers use nanoscale architecture to bend light and produce brilliant colors without pigments or dyes, and scientists have been trying to emulate nature's design.
Two research teams have made structures that could help conceal objects from daylight – taking the next step towards making the visible, invisible. Recent progress draws on advances in so-called metamaterials, which are ...
(Â鶹ÒùÔº)—Researchers have designed an optical lens that exhibits two properties that so far have not been demonstrated together: self-focusing and an optical effect called the Talbot effect that creates repeating patterns ...
In an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices, a team of University of Michigan researchers has developed a new technique that peppers ...
In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, ...
At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought. The discovery has implications in telecommunications. Working around ...
New findings in research funded by Morris Animal Foundation offer valuable insight on how to fight devil facial tumor disease (DFTD) that has resulted in a catastrophic decline in wild Tasmanian devils. Researchers have shed ...
Through advanced calculations physicists and mathematicians at the University of Twente discovered that a thin, diamond-like photonic nanostructure reflects a surprisingly broad range of colors of light, from all angles. ...
The concept of a perfect lens that can produce immaculate and flawless images has been the Holy Grail of lens makers for centuries. In 1873, a German physicist and optical scientist by the name of Ernst Abbe discovered the ...
Research conducted by scientists at Rochester Institute of Technology rules out a challenge to the accepted standard model of the universe and theory of how galaxies form by shedding new light on a problematic structure.
