Abstract
A power transmission system having a first resonant element with a resonant frequency, a signal generator that generates an electrical power signal with a predetermined frequency that is the same as the resonant frequency of the first resonator, and a driven element that supplies the electrical power signal to the first resonator via magnetic field resonance coupling. A second resonator having a resonant frequency approximately the same as that of the first resonator can be positioned to receive the power from the first resonator. A magnetic coupling circuit can be magnetic field resonance couple to the first and second resonators for transferring the electrical power signal between them.
