SUMMARY

A magnetron is a type of oscillator that generates microwaves by utilizing a cathode to emit electrons, which are then influenced by a magnetic field to move in a circular path around an anode. This anode contains cavities that are specifically tuned to create an electromagnetic field at a designated frequency. The process involves the interaction of the emitted electrons with the cavities, resulting in microwave production. Key resources for further understanding include the Wikipedia article on cavity magnetrons and a dedicated microtech website.

I have looked all of the internet trying to find how a magnetron produces microwaves to find nothing. Can anyone tell how a magnetron produces microwaves?
 
Science news on Phys.org
Look at the wikipedia article : http://en.wikipedia.org/wiki/Cavity_magnetron

A magnetron is an oscillator: electrons are boiled off the filament (cathode) and attracted to the anode, but that is surrounded by a magnet that forces the electrons to move in a circular path past a number of "cavities" in the anode - these are tuned so the create the EM field at a particular frequency
