Abstract (en)

[origin: WO2017137838A1] A method for improved wireless energy transfer includes steering a first energy beam, having a fundamental frequency, towards an energizable device. The first energy beam is formed by a plurality of polarizers of a first power access point (PAP). A first polarity of the first energy beam is aligned at the energizable device to a second polarity of a second energy beam formed by a second PAP, physically separate from, and having a wireless connection to, the first PAP, by combining at each of the polarizers of the first PAP a respective first polarized signal with a respective second polarized signal. The respective second polarized signal is formed by rotating the respective first polarized signal. The second PAP receives a PAP signal via the wireless connection and locally generates the fundamental frequency from the PAP signal.
