WiTricity by magnetic induction

Abstract

Performing two experiments for wireless transport of electrical energy (WiTricity) in the near field regions: reactive and Fresnel zone, in which the magnetic induction principle was applied and solenoids in a self resonant and coupling regime close to 1, were used, these showed be efficient in the transfer of electricity to distances up to 4 times the radius of the coil (Experiment 2, L1,2), with an efficiency of 60%. The article presents the design and results of research experience, likewise, it is discussed the practical applicability for future work.
