It is also possible to transmit power using non-radiative fields. As an example, the operation of a transformer can be considered a form of wireless power transfer since it uses the principle of magnetic induction to transfer energy from a primary coil to a secondary coil without a direct electrical connection. Inductive chargers, such as those found commonly in electric toothbrushes, operate on this same principle However, for these systems operate efficiently, the primary coil (source) and secondary coil (device) must be located in close proximity and carefully positioned with respect to one another. From a technical point of view, this means the magnetic coupling between the source and device c must be large for proper operation. To overcome the above challenges, that is, to transmit somewhat larger distances or have more freedom in positioning the source and device relative to each other, this paper explores the use of a non-radiative approach that uses resonance to enhance the efficiency of the energy transfer
