There are scenarios where Distributed Wireless Power Transfer (WPT) might be required to work without any steering (pilot signal) or information feedback from the power receiver. A new Sequential Phase Optimization (SPO) technique has been developed to create coherence from independent, distributed transmitters at the spatial location of a non-communicative power receiver. This would increase the efficiency of the power transfer compared to incoherent systems. The proposed technique was tested under laboratory conditions.
