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, wherein the first coil forms a first outline of a first surface; and
the receiver unit comprising a second electromagnetic resonator with a second coil coupled to a device load, wherein the second coil forms a second outline of a second surface shaped differently than the first surface,wherein at least one of the first surface or the second surface is a non-degenerate two-dimensional surface with at least one concave portion occupying three spatial dimensions, and wherein a 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 at an operating distance on opposite sides of a plane.
