    Abstract: Systems and techniques are provided for beamforming for wireless power transfer. A phase/amplitude map for a notional field in a plane of an aperture of the second wireless power transfer device may be determined. A Fourier transform may be performed on the phase/amplitude map for the notional field to generate a spatial frequency representation of the notional field. A phase/amplitude map for a second notional field in a plane of an aperture of the first wireless power transfer device may be determined based on the spatial frequency representation of the notional field and the position of the second wireless power transfer device. Control signals for transducer elements of the first wireless power transfer device may be generated based on the determined phase/amplitude map for the second notional field. The control signals for the transducer elements may be supplied to the transducer elements.
