Researchers at Germany's Karlsruhe Institute of Technology report they were able to cloak a tiny bump in a layer of gold, preventing its detection at nearly visible infrared frequencies.
Their cloaking device also worked in three dimensions, while previously developed cloaks worked in two dimensions, lead researcher Tolga Ergin said.
The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump in the gold later beneath, the researchers reported in Thursday's online edition of the journal Science.
In this case, the bump was tiny, a mere 0.00004 inch high and 0.0005 inch across, so that a magnifying lens was needed to see it.
"In principle, the cloak design is completely scalable; there is no limit to it," Ergin said. But, he added, developing a cloak to hide something takes a long time, "so cloaking larger items with that technology is not really feasible."
...
In earlier research, a team led by David Schurig at Duke University developed a way to cloak objects in two dimensions from microwaves. Like light and radar waves, microwaves usually bounce off objects, making them visible to instruments and creating a shadow that can be detected.
The new research led by Ergin used infrared waves, which are close to the spectrum of visible light.
In cloaking, special materials deflect radar, light or other waves around an object, like water flowing around a smooth rock in a stream. It differs from stealth technology, which does not make an aircraft invisible but reduces the cross-section available to radar, making it hard to track. |
It's a start.

 I'm not a bad enough dude, but I am an edgy little shit. I'll do what I can. |

It won't be long till they decide to unfreeze Hitler's head now.

We need this technology to keep pace with the Romulans!

So they made something that was already invisible to the naked eye, invisible to the naked eye. Go science!

Do stealth bombers not already use cloaking?
EDIT: Wait that's radar detection.. I'm an idiot.
