Abstract:
1. A contactless RF power coupling system comprising: a transmit coupling, wherein the transmit coupling includes a first canister that is electrically conductive and at least partially open at an end thereof, and a first resonant circuit having a first resonant frequency; a receive coupling, wherein the receive coupling includes a second canister that is electrically conductive and at least partially open at an end thereof, and a second resonant circuit having a second resonant frequency; and an RF source that provides the RF signal to the transmit couplings, the RF source comprising: wherein the transmit coupling receives an RF signal having a first frequency and a second frequency that is a harmonic frequency of the first frequency, and wherein the transmit coupling passes each of the first frequency and second frequency to the receive coupling when the transmit coupling and receive coupling are inductively coupled.
