Abstract
An electromagnetic cooking device includes an enclosed cavity; a set of radio frequency feeds configured to introduce electromagnetic radiation into the enclosed cavity to heat up and prepare food; a set of high-power radio frequency amplifiers coupled to the set of radio frequency feeds, each high-power amplifier comprising at least one amplifying stage configured to output a signal that is amplified in power with respect to an input radio frequency signal; a signal generator coupled to the set of high-power radio frequency amplifiers for generating the input radio frequency signal, and a controller. The controller can be configured to, among other things, cause the signal generator and selected ones of the set of high-power amplifiers to output a radio frequency signal, select from a set of phase values of radio frequency electromagnetic waves, and identify the resonant modes excited within the enclosed cavity.
