Abstract: An improved device and system for power transmission. A power transmission device comprises a primary winding magnetically coupled to a resonant secondary which comprises a plurality of magnetic resonators, each magnetic resonator comprising a magnetic winding. The magnetic resonators are connected in series and arranged so that the magnetic axis of each magnetic resonator is coupled to the primary winding. In operation, a power source supplies alternating current at an operating frequency to the primary of a power transmission device used as a transmitter. A load is coupled to the primary of a power transmission device used as a receiver. Collectors may be coupled to either or both of the transmit or receive device. A return line may be coupled to either or both of the transmit or receive device.
