How does microwave produced by magnetron relate to the power? For e.g., magnetron produces 3000 MHz microwave and power of the magnetron is 100 megawatt, how is this calculated (what is the relationship b/w frequency and power?) If the power (MW) of the magnetron is increased/or decreased, does that mean simply more/less # of microwaves are produced? Also, How does the amplitude of the electric field produced by the microwave relate to the frequency and power? How can that amplitude be changed by the magnetron? Thank you.
