Fractal Antenna Systems Inc. today announced successful demonstration of
the world’s first practical invisibility cloak, at microwave
frequencies. The device clearly shows the ability to “see through to the
other side” for large, 3-Dimensional objects, thus rendering them
invisible over a wide frequency range.
Previous invisibility cloaks were laboratory prototypes that commonly
cloaked paperclips, thimbles, plastic cylinders, or small objects, and
held no hope as practical devices. Also most cloak claims place the
object in shadow, or render them black, so they block the view to the
other side. In contrast, the firm’s new invisibility cloak, which leads
the convention for true invisibility, is not powered and has no
restriction of object placement. “It’s just what Harry Potter would
want,” said inventor, Nathan Cohen.
The invisibility cloak is built of tiny fractal patterns placed closely
together, using a technique first reduced to practice by the firm in
2008.
FRACTAL’s new 3D invisibility cloak is patent-pending, and is expected
to have many practical applications for “co-site” issues, for example.
Also, the cloak clearly indicates the technology can be used for
infrared and visible light wave lengths.
The new cloak was recently publicly demonstrated to visitors from Radio
Club of America and will be shown at public seminars in coming months.
A video of the new cloak can be seen at http://www.youtube.com/watch?v=2BrVxpPYMiA.
Cohen adds, “We also have something very exciting planned in the next
few weeks for those fans of invisibility.”
