Abstract
A method of delivering energy to an object in a cavity may include transmitting electromagnetic energy to the cavity at a plurality of frequencies. At each of the plurality of frequencies, the method may also include determining an efficiency of energy transfer into the object and adjusting power transmitted at each of the plurality of frequencies such that a multiplicative product of the efficiency and the power transmitted is substantially constant across each of the plurality of frequencies.
