W1YW Receives Patent for Electromagnetic "Invisibility Cloak"

Fractal Antenna Systems and its founder, Nathan "Chip" Cohen, W1YW, have been granted a U.S. patent for "deflective electromagnetic shielding." According to Southgate Amateur Radio News, quoting a December 19 story on "Business Wire," patent number 9,847,583 covers "electromagnetic cloaking/deflection of satellites, rockets, towers, antennas, vehicles, body coverings, people, ships, spacecraft, and many others, each uniquely recognized as novel inventions." The system uses closely-packed arrays of tiny fractal antennas to create surface waves that deflect electromagnetic signals - such as radar - around such objects as rockets, antennas, satellites and even people.
