A cavity resonator is one in which waves exist in a hollow space inside the device. In electronics and radio, microwave cavities consisting of hollow metal boxes are used in microwave transmitters, receivers and test equipment to control frequency, in place of the tuned circuits which are used at lower frequencies. Acoustic cavity resonators, in which sound is produced by air vibrating in a cavity with one opening, are known as Helmholtz resonators.
Rectangular or circular cavities can be used as microwave resonators because they have natural resonant frequency and behave like a LCR circuit. 121.How the cavity resonator can be represented by a LCR circuit?
