Scientists have taken another step toward the goal of rendering objects invisible using high-tech cloaks that redirect light.
Researchers for the first time demonstrated that a new material can bend visible light the wrong way in three dimensional tests. It builds on research that cloaks objects in the microwave wavelength.
The research, announced today, will be detailed later this week in the journals Nature and Science.
The metamaterial, as it is called, produces what's known as negative refraction of visible light. That means light is made to travel in the opposite direction from how it normally should bend when passing through a material. A common example is how a pencil will appear to bend upward when half-submerged in a glass of water. In the new work, researchers make the light appear to bend the other way.
Metamaterials are artificially engineered structures that have "extraordinary optical properties that do not exist in nature," the researchers write in Science. "They can alter the propagation of electromagnetic waves, resulting in negative refraction, subwavelength imaging and cloaking."

WOW, if it's getting published in Nature it is NOT bullshit. That's a peer reviewed journal.
I can't wait to hear what they come up with.

I've found this on the internet.
There are three video demonstrations on the site as well.
It looks interesting indeed. - 3 years ago

Wow, if that photo is not munipulated, that is pretty cool. The idea that they can refract light means that they are one step closer.
