Abstract: A wireless power transfer apparatus includes a first control system, a first energy transmission system, and a second energy transmission system. The first control system is coupled to the first energy transmission system, and inputs an energy transmission signal to the first energy transmission system. The first energy transmission system is coupled to the second energy transmission system, and inputs some of the energy transmission signals obtained from the first control system into the second energy transmission system. Both the energy transmission signal obtained by the first energy transmission signal from the first control system and an energy transmission signal obtained by the second energy transmission system from the first energy transmission system supply power to a target device.

Abstract: This application provides a wireless power transfer unit, device, and method. The wireless power transfer unit includes a radiation source, a light-emitting body, a controller, and a metasurface. The radiation source is configured to emit an electromagnetic wave signal. The controller is configured to control the light-emitting body to provide light sources of different light intensities. The light-emitting body provides the light sources of different light intensities in response to control of the controller. The metasurface is configured to perform phase adjustment on the electromagnetic wave signal that is incident to the metasurface. Equivalent impedance of the metasurface varies with a change of the light intensity, so that an offset of a phase of the electromagnetic wave signal emitted through the metasurface also varies with the change of the light intensity.

Abstract: A transmitter device (400), a receiver device (900), and a wireless charging method are provided. The transmitter device (400) includes a signaling modulation module (420), an energy modulation module (430), and an antenna element (440). The signaling modulation module (420) is configured to generate a narrowband modulation signal that carries signaling. The signaling includes an indication for a correspondence between a first resource and the receiver device (900). The first resource is scheduled based on a pre-received charging request signal from the receiver device (900). The energy modulation module (430) is configured to perform amplitude and phase adjustment on the narrowband modulation signal based on the pre-received charging request signal, to form an energy transmission signal. The antenna element (440) is configured to transmit the energy transmission signal on the first resource, to charge one or more receiver devices (900).
