  • Apparatus and method for microwave heating using chaotic signals
    Patent number: 6426487
    Abstract: An apparatus and method for heating microwave oven using a deterministic chaotic signal. The microwave oven includes a heating compartment, a magnetron for generating microwaves, a waveguide for directing the microwaves into the heating compartment and a chaotic signal generator for driving the magnetron. The characteristics of the chaotic signal are adjusted to tend to vary the output energy of the magnetron and increase the uniformity of the microwaves in the heating compartment.
