New Invisibility cloak prototype advances to 3-D

March 19, 2010

Indiana (ChattahBox) – An exciting development in cloaking technology, it’s now advanced to 3-D. Previous invisibility cloaks have already been developed but they only worked on two dimensions, so that objects that were supposed to be made invisible were immediately visible from the third dimension. Researchers from the German Karlsruhe Institute of Technology and Imperial College London have created the three-dimensional that can hide objects by bending light waves, which could pave the way for larger objects to be made invisible.

The “cloak”, described in the journal Science, made using photonic crystals with a structure resembling piles of wood that bend light waves to suppress it, rendered almost entirely invisible a bump that measured 0.00004 inches high by 0.00005 inches across. Tolga Ergin, who led the research said:

“The value of the finding is that we learn more about the concepts of transformation optics, and that we have made a first step in producing 3-D structures in that field.”

He cautioned that it likely be years before anything as large as a person, car or tank could be made to disappear with this technique.

    that’s what i’m talking about. lets get this out to the public!

  2. How do you go about getting a proto-type built for a new invention? on March 21st, 2010 10:05 pm
