Massachusetts Institute of Technology. Dept. of Physics. Physics. Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2009. Includes bibliographical references (leaf 49). In this dissertation, I describe the design and construction of a system which can transfer electric power wirelessly. This is accomplished using inductive, near-field, non-radiative coupling between self-resonant copper helices. In our first experiment, we transfered 60W of power over a distance of 2m with 45% efficiency. In our second experiment, we designed a system which can transfer power from a single source to two devices, each 2m away, with 60% total efficiency. We also developed a quantitative model of our helical resonators which predicted the resonant frequency with an accuracy of 5%. by Robert Alexander Moffatt.
