Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this ...

PITTSBURGH (KDKA) -- Without light, we can't have sight. We see objects because of how light interacts with those objects, our eyes pick up that light, and our brains interpret it. This seems rather ...

Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials ...

Invisibility used to be the stuff of comic books and Harry Potter novels. But this week, scientists from UC Berkeley have emerged with two new invisibility-producing “metamaterials,” engineered ...

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we’ll need to know more about how these weird metamaterials actually work. Michigan Tech ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Long the stuff of fantasy, practical invisibility shields have been brought a step closer to reality by researchers who say they have engineered materials that can hide an object by bending ordinary ...

PORTLAND, Ore. — The pursuit of so-called invisibility cloaks has spawned a new field called transformation optics that seeks to harness exotic metamaterials, nanophotonics and plasmonics to build ...

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 researchers has developed a new technique that peppers ...
