Eventually the Germans duplicated the magnetrons (now the source in ALL microwave ovens as well as most Radar) even though the unit had explosive charge to destroy it when the aircraft would be shot down.
They are a simple to make device the Victorians could have made. The modern ones in a microwave are simpler. I have one out of an oven and I used to have a 1948 model. See Wikipedia.
It's true you'd be ill without any of the vitamins in carrots. BTW, carrots used to be almost white.
