Abstract: Embodiments described herein may relate to a system including a transmit resonator configured to couple power from a source into an oscillating field generated with a reference phase by the transmit resonator resonating at an oscillation frequency; one or more repeaters, each at a respective location, each including: a repeat resonator configured to resonate at the oscillation frequency, where each of the one or more repeaters is configured to regenerate the oscillating field with a phase shift relative to a phase at the respective location; and at least one receiver, the at least one receiver including: a receive resonator configured to resonate at the oscillation frequency in response to coupling to the oscillating field, where the at least one receiver is configured to transfer a power of the oscillating field to a load associated with the at least one receiver.

Abstract: Embodiments described herein may relate to a system comprising a power source configured to provide a signal at an oscillation frequency; a transmitter coupled to the power source, wherein the transmitter comprises at least one transmit resonator; one or more receivers, wherein the at least one receive resonator is operable to be coupled to the transmit resonator via a wireless resonant coupling link; one or more loads, wherein each of the one or more loads is switchably coupled to one or more respective receive resonators. The system includes a controller configured to determine an operational state of the system, wherein the operational state comprises at least one of three coupling modes (common mode, differential mode, and inductive mode), and is configured to cause the transmitter to provide electrical power to each of the one or more loads via the wireless resonant coupling link according to the determined operational state.
