S-band high power pulsed magnetron

By adjusting the diameter ratio of the anode tube and the cathode emitter, as well as the anode voltage, and combining this with the magnetic field provided by the permanent magnet, the connection point between the anode blade and the antenna was optimized. This resulted in a small-volume, high-power S-band magnetron, resolving the contradiction between volume and power in existing technologies and expanding application scenarios.
