a conducting surface enclosing a space in which an oscillating electromagnetic field can be maintained, the dimensions of the cavity determining the resonant frequency of the oscillations. It is used in microwave devices for frequencies exceeding 300 megahertz
Also called: resonant cavity, rhumbatron
