摘要
An electromagnetic cooking device and cooking method to perform zone cooking is disclosed. The method includes scanning a resonant cavity in which a food load has been placed with RF feeds that are coupled to respective high power amplifiers; identifying resonant frequencies and corresponding phases of the RF feeds; 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; 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 and RF feeds to introduce electromagnetic radiation at specific selected frequencies and phases into the cavity based on the heating strategy.
