Claim 0:
1. A wireless power transfer system, comprising:
a first resonator;
a repeater resonator configured to inductively couple to the first resonator and to receive electromagnetic energy from the first resonator, wherein the repeater resonator has a length from a first end of the second end, wherein the repeater resonator forms a circular configuration with the first end adjacent to the second end, wherein the repeater resonator includes a series of coils arranged uniformly along the length of the repeater resonator is uniform along the length of the repeater resonator such that the inductive coupling between the repeater resonator and the first resonator is independent of an angular position of the repeater resonator; and
a second resonator configured to inductively couple to the repeater resonator and to receive electromagnetic energy from the repeater resonator, wherein the inductively coupling between the second resonator and the repeater resonator is independent of the angular position of the repeater resonator;
wherein the repeater resonator is configured to be worn as a belt around a subject within whom a medical device and the second resonator are implanted such that the series of coils is distributed around the subject, the repeater further configured to transfer power to the second resonator through a skin of the subject;
wherein the series of coils of the repeater resonator are electrically coupled together in a series configuration.
