Cloak of invisibility almost a reality

Cloak of invisibility almost a reality just like in the movies and games. From Harry Potter's the cloak of invisibility, to other sci-fi and fantasy movies. Now scientists have taken a small but important new step toward making it reality.
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.

"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."
"Other fabrication techniques, though, might lead to larger cloaks."

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.

Ergin's research was supported by the German Research Council, the state of Baden-Wuerttemberg, the European Commission and the German Ministry for Education and Research.
