cavity tuning

cavity tuning

[′kav·əd·ē ‚tün·iŋ]
(electromagnetism)
Use of an adjustable cavity resonator as a tuned circuit in an oscillator or amplifier, with tuning usually achieved by moving a metal plunger in or out of the cavity to change the volume, and hence the resonant frequency of the cavity.

Although the importance of the impedance matching and cavity tuning has been already found and discussed in medicine for microwave exposure to biological tissue [12] (at, obviously, a low temperature), those aspects are rarely evoked in hightemperature microwave processes.
