What type of circuit is a cavity resonator?
In either case, cavity resonators are a particular type of resonator that consists of a closed or mostly closed metal structure that confines electromagnetic fields in the microwave region of the spectrum.
What does a cavity resonator do?
A cavity resonator can be used as a frequency sensor. It acts as an energy trap, because it will siphon off energy from a microwave when the microwave frequency hits the resonance frequency of the cavity resonator.
How does the resonance occur in a cavity resonator?
A cavity resonance occurs inside a conductive enclosure when energy is generated at frequencies which correspond to the resonant frequencies of the enclosure. At the cavity resonance frequencies the resonance can provide a secondary coupling path between the energy source and a victim.

What is Q of a resonator?
The quality factor (Q) of a resonator is expressed as the ratio of stored versus lost energy per oscillation cycle. Overall losses through a resonator increase as Q factor drops and will increase more rapidly with frequency for lower values of resonator Q.
What is Q of cavity?
The Q factor of the cavity resonator is the ratio between the stored energy of the cavity to the power loses in the cavity.
What is a RF resonator?
A microwave cavity or radio frequency (RF) cavity is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave region of the spectrum. The structure is either hollow or filled with dielectric material.
What is resonator English?
Definition of resonator : something that resounds or resonates: such as. a : a hollow metallic container for producing microwaves or a piezoelectric crystal put into oscillation by the oscillations of an outside source. b : a device for increasing the resonance of a musical instrument.
Which method is used to measure Q of cavity resonator?
Q-factor measurement by the cavity resonator method By measuring RF power from port 1 and port 2 of the metal cavity, scattering matrix S21 can be determined with frequency scan. S21 is the ratio of the voltage measured at port2 compared to the voltage generated at port1.
What does high Q factor of an optical cavity means?
Q Factor is proportional to the ratio of the energy stored inside the standing wave and the wasted energy from the wave during round trip between the laser mirrors. High Q Factor value means that the energy is stored well inside the cavity. Low Q Factor value means that the energy is emitted from the cavity rapidly.
