1. A system for wireless energy transfer comprising:
- a transmitter unit comprising a first electromagnetic resonator with a first coil configured to be coupled to a power supply to wirelessly transmit power through a magnetic flux to a receiver unit; and
a receiver unit comprising a second electromagnetic resonator with a second coil coupled to a device load, wherein at least one of the first and second electromagnetic resonators is a non-planar electromagnetic resonator that conforms to a non-degenerate two-dimensional surface with at least one concave portion and wherein the shape of the non-degenerate two-dimensional surface is configured to shape the magnetic flux to increase a coupling between the electromagnetic resonators over different orientations of the electromagnetic resonators.

Abstract
A system for omni-orientational wireless energy transfer is described. A transmitter unit has a transmitter resonator with a coil that is configured to be coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. At least one of the resonators is a non-planar resonator that spans a non-degenerate two-dimensional surface having at least one concave portion.
