Abstract

An electromagnetic cooking device (10) and cooking method to perform zone cooking is disclosed. The method includes scanning a resonant cavity (20, 222) in which a food load has been placed with RF feeds (26A-26D, 226A, 226B) that are coupled to respective high power amplifiers (18A-18D); identifying resonant frequencies and corresponding phases of the RF feeds (26A-26D, 226A, 226B); storing a resonance map; classifying symmetries in the resonant map; determining paths defining stirring routes between poles of different symmetries; determining midpoints in the paths with a maximum unbalance between reflected powers of the respective high power amplifiers (18A-18D); classifying the unbalance in terms of power steered to the left and right sides of the food load; synthesizing a heating strategy for zone cooking using the classified unbalance; and implementing the heating strategy by causing the plurality of high power amplifiers (18A-18D) and RF feeds (26A-26D, 226A, 226B) to introduce electromagnetic radiation at specific selected frequencies and phases into the cavity (20, 222) based on the heating strategy.
