Invisibility cloak makes stuff disappear in three

After plugging away for some time at two dimensional invisibility cloaks, researchers have begun experimenting with a cloak that can obscure its contents in three dimensions. While the device only works in a limited range of wavelengths, its relative success should help keep the field moving forward. The invisibility cloaks mentioned among scientists are not really turning anything invisible, but rather playing tricks with the light, misdirecting it so that the objects they encase cannot be seen. Normally, the cloaks only work in two dimensions, so just by changing your point of view a bit, the cloak will become obvious—a limitation scientists want to overcome. The 3D cloak in this case is made of woodpile-structured photonic crystals that can redirect light of wavelengths around the size of the crystals' rod spacing

There was an Iranian scientist involved

by Anonymous Observer on

in a project like this that I read about  a few years ago.  He was working on a uniform that would make soldiers invisible.  He was a professor out of some university in Pennsylvania.  He was also a graduate of Tehran University.  I just googled the information, but couldn't find the news piece.  I remember it was posted on MSNBC.

They will steal this technology as we have seen on Star Trek
