摘要： An electromagnetic cooking device is provided having a controller and a plurality of RF feeds configured to introduce electromagnetic radiation into an enclosed cavity to heat up a food load. The controller is configured to: select a heating target; generate a heating strategy to determine a sequence of desired heating patterns; cause the RF feeds to output an RF signal to thereby excite the enclosed cavity; monitor the created heating patterns to measure resonances in the enclosed cavity and store a map of efficiency in frequency and phase domains from which the controller identifies resonant modes and Q-factors associated therewith; continue to monitor the created heating patterns and store maps of efficiency in the frequency and phase domains until a specified change is detected in at least one Q-factor; and when the specified change in the at least one Q-factor is identified, stop cooking the food load.

摘要： A method for identifying a cooking level of a food load in an electromagnetic cooking device is disclosed. The method comprises controlling a frequency and a phase of a first RF signal and a second RF signal and amplifying the first RF signal and the second RF signal thereby generating a first RF feed and a second RF feed. The method further comprises emitting the first RF feed and the second RF feed into an enclosed cavity to heat a food load and measuring at least one reflection signal. The method further comprises calculating a Q-factor for the enclosed cavity based on the reflection signal, monitoring the Q-factor, and identifying a change in the Q-factor exceeding a predetermined change threshold. In response to identifying the change exceeding the predetermined change threshold, a cooking level for the food load is identified.
