WIRELESS POWER TRANSFER USING AIR GAP AND METAMATERIAL
First Claim
1. An apparatus for transmitting power to a vehicle, the apparatus including:
- a power transmitter, including a transmitter coil and a first metamaterial lens; and
a power receiver, including a receiver coil and a second metamaterial lens, the power receiver being located within the vehicle,the first and second metamaterial lenses each having a negative magnetic permeability,the apparatus being operable to transmit electromagnetic radiation from the transmitter coil to the receiver coil when the transmitter coil is energized,the electromagnetic radiation from the transmitter coil being focused on the receiver coil by the combination of the first and second metamaterial lenses.

Abstract
Examples of the invention include methods and apparatus for wirelessly transmitting power to a vehicle using electromagnetic radiation. An example apparatus includes a transmitter coil associated with a first metamaterial lens, and a receiver coil associated with a second metamaterial lens, the receiver coil being located within the vehicle. The metamaterial lenses each have a negative magnetic permeability, and are separated by a lens spacing including an air gap. The first and second metamaterial lenses (and the lens spacing) act cooperatively to focus the electromagnetic radiation from the transmitter coil on the receiver coil.
