Abstract
The invention provides a device and method for wireless transmission of energy. An electromagnetic field used for transmitting energy is generated using a resonator system comprising a plurality of weakly coupled resonators, the resonator system having a plurality of eigenmodes with different eigenfrequencies. At least one generator is coupled to one of the resonators. The resonator is configured to operate the resonator system at one of the plurality of eigenmodes, thereby generating a spatially coherent magnetic field adapted for transmitting energy to an appliance.
