Breakthrough demonstrations of invisibility cloaks, including a wearable invisibility cloak/deflector shield, were presented at the Radio Club of America Technical Symposium in New York City on November 16.
Previously a science fiction premise, invisibility cloaks are passive devices that divert electromagnetic waves around an object, rendering it invisible. Accomplishing this successfully has been pioneered, using radio microwaves, by Fractal Antenna Systems of Waltham MA. The firm uses its proprietary fractal based technology to make fractal metamaterial for a unique advantage in invisibility cloaks, antennas, and other electronic devices.
Starting with a symposium presentation of wideband, thin, and shadow-less invisibility cloaks, Nathan Cohen, inventor and physicist, and CEO of Fractal Antenna Systems, proceeded with a video of the world’s first cloaking of a man.
But more was to come.
That would have been a cool event to attend. To read more, click here.
