Radial waveguide systems and methods for post-match control of microwaves
First Claim
1. A system that generates microwaves in a waveguide, comprising:
- the waveguide;
one or more transmitters that transmit;
a first microwave signal into the waveguide at a first location, anda second microwave signal into the waveguide at a second location,at least one monitoring antenna within the waveguide that provides an analog signal responsive to microwaves at a location of the monitoring antenna; and
a controller that receives the analog signal, and in response to the analog signal, adjusts at least one of a phase and an amplitude of the first microwave signal or the second microwave signal, until the analog signal meets a predetermined condition.

Abstract
A system provides post-match control of microwaves in a radial waveguide. The system includes the radial waveguide, and a signal generator that provides first and second microwave signals that have a common frequency. The signal generator adjusts a phase offset between the first and second signals in response to a correction signal. The system also includes first and second electronics sets, each of which amplifies a respective one of the first and second microwave signals. The system transmits the amplified, first and second microwave signals into the radial waveguide, and matches an impedance of the amplified microwave signals to an impedance presented by the waveguide. The system also includes at least two monitoring antennas disposed within the waveguide. A signal controller receives analog signals from the monitoring antennas, determines the digital correction signal based at least on the analog signals, and transmits the correction signal to the signal generator.

12. A signal corrector that provides a correction signal for a microwave generator that transmits microwaves, at a microwave frequency, into a microwave chamber from at least two locations, the signal corrector comprising:
-
a first clock generator that produces the microwave frequency; a second clock generator that produces a control signal; a decoder that produces one or more digital signals in response to at least one analog signal from a location within the microwave chamber, at each cycle of the control signal; and a microcontroller that generates the correction signal based at least in part on the one or more digital signals, wherein the correction signal specifies an adjustment, by the microwave generator, for at least one of a phase and an amplitude of the microwaves transmitted into the microwave chamber. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
