Abstract
Implementations described herein provide systems and methods for wireless charging. In one implementation, a base has a planar surface. One or more posts extend from the planar surface of the base to form a core. Each of the one or more posts is formed from a plurality of nanocrystalline sheets. The plurality of nanocrystalline sheets of each of the one or more posts is oriented in planes perpendicular to the planar surface of the base. One or more coils are wound around each of the one or more posts to form coil windings.
