While vacuum electronic devices have largely been superseded over much of consumer electronics, there’s one place where they can still be found for now. The cavity magnetron is a power RF oscillator ...
Abstract: We present a simple design method for the hole-slot-type cavity magnetron. Our design model includes all principal parts of magnetron, namely, the cathode, the resonant system, the ...
It may seem like a holdout against the solid-state world, but the vacuum-tube magnetron is still at the heart of every consumer microwave oven and many commercial ones used for cooking or drying.
