An electromagnetic cooking device includes an enclosed cavity configured to receive a food load, a plurality of high power amplifiers and RF feeds for introducing electromagnetic radiation into the cavity, and a controller for controlling the frequency, phase and amplitude of the electromagnetic radiation fed into the cavity by the RF feeds. The controller is configured to identify resonant modes, develop and implement a heating strategy based on the resonant modes, utilize an asynchronous manager to automatically detect when a variable has changed to a degree that requires an updated identification of resonant modes and an updated heating strategy, and if the asynchronous manager determines that updates are needed, repeat the steps above to determine a new heating strategy, otherwise continue with the current heating strategy.
