DYNAMIC IMPEDANCE MATCHING IN RF RESONATOR CAVITY

摘要

A method for matching an impedance of a system comprising a cavity and one or more feeds to an impedance of one or more sources of electromagnetic radiation irradiating a plurality of frequencies into the cavity via the feeds, comprising: determining a plurality of s-parameter of the system for a frequency band; determining the system impedance based on the s-parameters; and modifying the system impedance according to the difference between the impedance of the system and the impedance of the source.

1. A method for improving absorption of electromagnetic energy provided by a source at a plurality of frequencies within a frequency band into a cavity via feeds in a system comprising the cavity and the feeds, comprising:
(a) determining s-parameters of the system comprising the cavity and the feeds for a plurality of frequencies in the frequency band; (b) determining an absorption intensity characteristic of an entirety of the frequency band, based on the s-parameters determined for the plurality of frequencies in the frequency band; and (c) improving the absorption intensity characteristic of the frequency band by changing phases of RF signals directed to the feeds.
