  • Patent number: 4196332
    Abstract: A frequency controlled microwave oven having an oven cavity, a frequency agile microwave source for energizing the oven cavity, a detector for detecting the power absorption in a load at various source frequencies within a bandwidth and a control circuit for setting the microwave source at frequencies as determined by the power absorption levels. The frequencies at which the oven cavity is energized are selected by the control system to obtain high efficiency, i.e. low power reflection from the cavity, and to obtain improved heating uniformity by the superimposing of various heating patterns produced by the different operating frequencies.
