Spray-On Form-Fitting Antennas and EM Filters
Scientists at the Raytheon-UMass Lowell Research Institute (RURI) have developed printable inks for producing tunable, electromagnetic filters on a variety of surfaces. The result can be printed directly on military equipment, including tanks, armored vehicles, and aircraft, serving as anything from a radio antenna to a radar array to even an “invisibility cloak”.
