Abstract
A repeater for a wireless power transfer system is disclosed. The repeaters includes an elongated strip of material arranged in a substantially circular configuration with opposing ends of the elongated strip disposed in close proximity to each other, an inductive element associated with the elongated strip and arranged to provide a coupling with an adjacent resonator through flux directed outward from a first surface of the elongated strip, and a capacitive element associated with the elongated strip and arranged to resonate electromagnetic energy with the inductive element when the electromagnetic energy is transferred from the adjacent resonator through the coupling provided by the inductive element.

A wireless power transfer system, comprising:
- a first resonator,
- a repeater resonator is configured to inductively couple to the first resonator and to receive electromagnetic energy from the first resonator, wherein the repeater resonator has a length from a first end to a second end, wherein the repeater resonator forms a circular configuration with the first end adjacent to the second end, wherein the repeater resonator comprising an inductive track or series of coils arranged uniformly along the length of the repeater resonator such that an amount of flux directed outward from a first surface of the repeater resonator is uniform along the length of the repeater resonator such that the inductive coupling between the repeater resonator and the first resonator is independent of an angular position of the repeater resonator;
- and
- a second resonator configured to inductively couple to the repeater resonator and to receive electromagnetic energy from the repeater resonator, wherein the inductive coupling between the second resonator and the repeater resonator is independent of the angular position of the repeater resonator.
An apparatus comprising:
- a repeater resonator having a first end and second end and formed in a circular configuration with a first end adjacent to a second end, wherein the repeater resonator includes an inductive track or a series of coils arranged uniformly along the repeater resonator from the first end to the second end such that an amount of flux directed outward from a first surface of the repeater resonator is uniform between the first end and the second end, wherein the repeater resonator is configured to inductively couple to a first resonator to receive first electromagnetic energy independent of an angular position relative to the first resonator and inductively couple to a second resonator to provide second electromagnetic energy independent of an angular position relative to the second resonator based on the first electromagnetic energy.
A method comprising:
- receiving, at a repeater resonator, first electromagnetic energy from a first resonator via inductive coupling between the first resonator and a first coil of an inductive element or a series of coils arranged uniformly along the repeater resonator from a first end to a second end;
- and
- providing, from the repeater resonator, second electromagnetic energy to a second resonator based on the first electromagnetic energy via inductive coupling between the second resonator and a second coil of the series of coils.
