SYSTEMS AND METHODS FOR WIRELESS POWER TRANSFER
First Claim
1. An apparatus for use with a wireless power transfer system, comprising:
- one or more ferromagnetic, ferrite, or other magnetic materials or layers, that are used to modify the magnitude and/or phase of an electromagnetic field and/or corresponding magnetic flux in one or multiple dimensions and/or to guide the magnetic flux in such a manner as to create a preferential path for flux flow, for use in wireless charging or power transfer.

Abstract
Systems and methods for enabling efficient wireless power transfer, and charging of devices and batteries, in a manner that allows freedom of placement of the devices or batteries in one or multiple (e.g., one, two or three) dimensions. In accordance with various embodiments, applications include inductive or magnetic charging and power, and wireless powering or charging of, e.g., mobile, electronic, electric, lighting, batteries, power tools, kitchen, military, medical or dental, industrial applications, vehicles, trains, or other devices or products. In accordance with various embodiments, the systems and methods can also be generally applied, e.g., to power supplies or other power sources or charging systems, such as systems for transfer of wireless power to a mobile, electronic or electric device, vehicle, or other product.
