Abstract
A circuit for transferring wireless electrical energy through a lossy material is described. The circuit comprises a first inductive winding portion connected electrically in series to a second inductive winding portion and at least one capacitor. Interaction of the first or second inductive winding portions with an electromagnetic field emanating from an electrical power source causes electrical energy to be induced within the circuit. The first inductive winding portion is preferably positionable adjacent a first sidewall of a lossy material and the second inductive winding portion is preferably positionable adjacent the second and opposite sidewall of the lossy material. At least one intermediate substrate composed of a ferrite material is preferably positioned between the first and second inductive winding portions as a shield that minimizes electromagnetic field interference.
