Abstract
An electromagnetic heater for heating an irregularly shaped object, including: a cavity within which an object is to be placed; at least one feed which feeds UHF or microwave energy into the cavity; and a controller that controls one or more characteristics of the cavity or energy to assure that the UHF or microwave energy is deposited uniformly in the object within ±30% over at least 80% of the volume of the object.

1-26. (canceled)
Apparatus for electromagnetic heating comprising:
- a cavity;
- a plurality of feeds configured to feed UHF or microwave energy into the cavity;
- and
- a controller configured to determine an efficiency of net power transfer into the cavity and adjust transmitted frequencies of a plurality of inputs to control the efficiency of net power transfer into the cavity, wherein the controller is further configured to adjust input power to the plurality of feeds at one or more transmitted frequencies based on the efficiency of net power transfer into the cavity.

A method of electromagnetic heating comprising:
- placing an object to be heated into a cavity;
- feeding UHF or microwave energy into the cavity via a plurality of feeds;
- determining an efficiency of net transfer of energy into the cavity for each of the plurality feeds as a function of frequency over a range of frequencies;
- adjusting transmitted frequencies of the UHF or microwave energy fed into the cavity based on the determined efficiency of net transfer of energy into the cavity;
- and
- adjusting input power to the plurality of feeds at one or more transmitted frequencies based on the efficiency of net power transfer of energy into the cavity.
