Resonator

From Glossary of Meteorology



resonator

In radio and radar applications, a circuit that will resonate at a certain frequency, or over a range of frequencies, when properly excited.

An important type of resonator is the cavity resonator, a closed hollow volume having conducting walls. The frequency at which such cavities resonate is a function of their volume and shape. They are used for making accurate frequency comparisons and for generating radio frequencies, usually in the microwave region.
