This wideband retroreflector provides signal retransmission with low power in a compact design. This invention can signifigantly improve communications and remote-sensing applications including air traffic control, ground-to-satellite communications, and high-rate data transfer from radio-frequency identification (RFID) sensors. The system also improves communications by enhancing signals in areas with weak wireless reception. The compact design makes it easy to deploy and maintain in remote locations. Additionally, this lower-powered technology handles high-bandwidths more effectively than current systems.
Potential applications include: remote or dangerous area data collection; vehicle-to-vehicle, or vehicle-to-stationary object communication, unmanned aerial vehicle swarms, and gamification.
- Eliminates the power requirements of a local oscillator and does not suffer the limitations on switching speed of non-linear junctions
- Data transfer by the illumination of the retroreflector with a continuous wave of RF energy, where the retroreflector both modulates the incoming signal and retransmits it using the incoming signal energy
- US patent 7,383,026 available for license
- Potential for collaboration with NSA scientists and engineers
