DEFINITION

Classification: 315/39.75

(under subclass 39.51) Devices in which the anode is provided with a cavity which due to its geometry and its electrical properties, is resonant.

(1) Note. The anode may be a circular block having therein a resonant cavity, or it may be a circular structure formed with vanes, the space between the vanes forming a resonant cavity.

(2) Note. This subclass includes magnetrons with the specified type of electrode, and also the electrode, per se.
