1. An apparatus for wireless energy and/or data transmission between a source device and at least one target device, the apparatus comprising:
- at least one primary coil, on the source-device side, of at least one primary circuit;
at least one secondary coil, on the target-device side, of at least one secondary circuit;
a first resonator having a first resonant circuit with a first resonant circuit coil and a first capacitor, the first resonant circuit being electrically isolated from the primary circuit and from the secondary circuit; and
at least a second resonator having a second resonant circuit with a second resonant circuit coil and a second capacitor, the second resonant circuit being electrically isolated from the primary circuit and from the secondary circuit and from the first resonant circuit, at least one of the first and second resonators has a resonant frequency which is different from the frequency of an energy source arranged in the primary circuit, the resonant frequency being twice or 0.5 times the frequency of the energy source;
wherein the primary coil, the secondary coil, the first resonant circuit coil, and the second resonant circuit coil are arranged in the same magnetic circuit.
