Abstract: A wireless power transfer system may include a primary resonator and one or more secondary resonators. At least one of the secondary resonators lie in overlapping relation to the primary resonator. An electromagnetic (EM) field generated by the primary resonator can couple to the secondary resonators, thus inducing current flow in the secondary resonators. EM fields generated by the secondary resonators interact with the EM field from the primary resonator to produce a resultant EM field.
