Whisper Beam UAV Power Transfer

Whisper Beams use a new "non-gaussian" electromagnetic wave that focuses itself at the intended receiver, making it economic and practical to deliver kilowatts of power at kilometer distances. A UAV can carry a compact receiver to draw power while in flight. Swarms of UAVs can form a transmission array relaying power over several kilometers, such as from a main base to a forward base.     With DARPA SBIR Phase I funding, we will build and demonstrate the first radio-frequency Whisper Beam transmitter at a lab-bench scale,powering a short-range UAV in flight. The technology readily scales to power large UAV swarms at kilometer altitudes, and/or wirelessly transfer power from a main base to a forward base several kilometers away. We will also analyze swarm patterns to optimize power levels over long distances.
