ScienceDaily (May 2, 2009) — The great science fiction writer Arthur C. Clarke famously noted the similarities between advanced technology and magic. This summer on the big screen, the young wizard Harry Potter will once again don his magic invisibility cloak and disappear. Meanwhile, researchers with Berkeley Lab and the University of California (UC) Berkeley will be studying an invisibility cloak of their own that also hides objects from view.
A team led by Xiang Zhang, a principal investigator with Berkeley Lab’s Materials Sciences Division and director of UC Berkeley’s Nano-scale Science and Engineering Center, has created a “carpet cloak” from nanostructured silicon that conceals the presence of objects placed under it from optical detection. While the carpet itself can still be seen, the bulge of the object underneath it disappears from view. Shining a beam of light on the bulge shows a reflection identical to that of a beam reflected from a flat surface, meaning the object itself has essentially been rendered invisible.
“We have come up with a new solution to the problem of invisibility based on the use of dielectric (nonconducting) materials,” says Zhang. “Our optical cloak not only suggests that true invisibility materials are within reach, it also represents a major step towards transformation optics, opening the door to manipulating light at will for the creation of powerful new microscopes and faster computers.”

When they work out the IR problem this could be useful.
“... the cloak was used to cover an area that measured about 3.8 microns by 400 nanometers.”
LOL, that’s submicroscopic!
Dude, get some reading glasses.
And Bill Clinton will be caught using it to sneak into the girl’s locker room at the local college. What gave him away was one of the girls heading into the shower heard a raspy voice from nowhere utter, “Man! Harry Potter didn’t know what he was missin’! Heh-heh-heh!”
LOL
Here’s a picture of the invisibility cloak:
Amazing technology! It is truly beautiful!
best,

Ping me Einstein!
You gotta be kidding?!!!!!
And people walked by it all day without seeing it. Amazing!
Hey, it’s a REAL stealth plane!
Is this for real? And if so, how long has it been unknown to the public?
bttt
