Invisibility Cloak Created In 3-D

Posted by kdawson on from the can-you-see-me-now dept.

An anonymous reader writes "Scientists have created the first device to render an object invisible in three dimensions. The 'cloak,' described in the journal Science (abstract; full text requires login), hid an object from detection using light of wavelengths close to those that are visible to humans. Previous devices have been able to hide objects from light travelling in only one direction; viewed from any other angle, the object would remain visible. This is a very early but significant step towards a true invisibility cloak." The "object" hidden in this work was a bump one micrometer high. The light used was just longer than the wavelengths our eyes detect. To get a visible-light cloak, the features of the cloaking metamaterial would need to be reduced in size from 300 nm to 10 nm.

    ... so far not even a 3d cloak could hide her!

    I think you're doing it wrong.

    all it really took to accomplish "Invisibility Cloak Created In 3D", was to redefine the terms "invisibility", "cloak" and "created" in new, creative ways that fit what they actually did.

    Why does science need a reason? Once we have this stuff people will dream up creative aplications you or I could never have dreamed of.
