Using self-resonant coils in a strongly coupled regime, we experimentally demonstrated efficient nonradiative power transfer over distances up to 8 times the radius of the coils. We were able to transfer 60 watts with ∼40% efficiency over distances in excess of 2 meters. We present a quantitative model describing the power transfer, which matches the experimental results to within 5%. We discuss the practical applicability of this system and suggest directions for further study.

A novel resonator for simultaneous Wireless Power Tranfer and Near Field Magnetic Communications

This work presents a novel structure that can be used for both WPT and NFMC, and shows a dual band transmission channel allowing a frequency separation of the power channel and of the data channel, thus enabling simultaneous transmission of power and data.

Resonant Wireless Power Transfer: Investigation of radiating resonances

Resonant Wireless Power Transfer is an emerging technique for exchanging energy in the near field. Common resonators take the form of splitted ring resonators, coils, spiral, or helical resonators.

Wireless transmission of power and information and information for cableless linear motor drive

This paper describes the basic concept of the WTPI and the analysis on the performance of theWTPI configured in the linear shape, thereafter introducing the preliminary test result on a prototype of the cableless linear pulse motor (CLLPM) which was constructed by integrating alinear pulse motor with the associated driver and the linear WTBI for noncontact motion transfer.

Observation of strong coupling between one atom and a monolithic microresonator

Strong coupling is achieved, with the rate of coherent coupling exceeding the dissipative rates of the atom and the cavity, and this work opens the way for investigations of optical processes with single atoms and photons in lithographically fabricated microresonators.
