We will describe results of our theoretical, and experimental work on WiTricity: a technique for wireless power transfer using strongly-coupled long-lived electro-magnetic resonances.
In this scheme, both the power source and the device receiving the power are electromagnetic resonators, oscillating at the same resonant frequency. Instead of irradiating the environment with electromagnetic waves, the source fills the space around it with a "non-radiative" near-field. The crucial advantage of using the non-radiative modes lies in the fact that most of the power not picked up by the device remains bound to the vicinity of the source, instead of being radiated into the environment and lost. This technique could potentially be used for middle-range power transfer, such as within a room, or a factory pavilion.
