Abstract:
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 at least one feed in a system comprising the cavity and the at least one feed, comprising: (a) determining s-parameters of the cavity and the at least one feed 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 varying an impedance by a determined impedance change, that results in improvement in the absorption intensity characteristic, by varying an impedance of at least one of: the cavity, the at least one feed, or impedance circuitry positioned between the source and one of the at least one feed wherein the impedance circuitry comprises at least one of: RC circuitry, RL circuitry, LC circuitry, RLC circuitry, and balun transformer.
