Abstract: A heating profile of a microwave oven is modified using microwaves at a plurality of frequencies. A power of transmission to a cavity of the microwave oven of microwaves is defined at each of the plurality of frequencies. A duration is defined for which the microwaves are transmitted at each of the plurality of frequencies. For each of the plurality of frequencies, a proportion of power input to the cavity that is not output from the cavity is measured. The measured proportions am used to modify the power of transmission at each frequency, the duration of transmission at each frequency or both.
