1. A system for wireless energy transfer comprising:
- a transmitter unit including a first electromagnetic resonator having a first coil configured to wirelessly transmit power through a magnetic flux, wherein the first coil is rigidly shaped to form a first outline of a first surface; and
a receiver unit including a second electromagnetic resonator having a second coil configured to wirelessly receive power through the magnetic flux, wherein the second coil is rigidly shaped to form a second outline of a second surface;
wherein at least one of the first surface or the second surface is a non-planar surface occupying three spatial dimensions, and wherein the non-planar surface shapes the magnetic flux to wirelessly transfer power when the rigidly shaped first coil and second coil and physically decoupled and freely movable relative to each other.

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.
