Signature Reduction using Metasurfaces on group 1 UAV platforms

Enemies use radar system to identify and target Unmanned Aerial Vehicles (UAVs). To prevent detection, the UAV should be able to reduce its RF signature by reducing its Radar Cross Section (RCS). In addition, it is essential for the "blue force" UAV to be able to use its RF systems (radar/comms) while not being detected. Traditional Radar Absorbing Materials (RAM) are used to absorb radar's Electromagnetic energy to reduce an aircraft's RCS but this material can be thick, heavy, and have high material and maintenance costs. Notch's metasurface technology can controllably absorb enemy radar, reducing the UAV's RCS, while allowing for the UAV to operate its own onboard RF systems and carry out its mission. Notch's metasurface technology is light-weight, inexpensive to manufacture and software controllable.
