Never mind, I found plenty. Sure seems to be a lot of heat coming from my microwave oven magnetron. I gues no one has really done the calorimetry. BTW, I am struck by the graphic similarity of these two cross sections: http://www.iter.org/what.htm http://home.cvc.org/microwaves/HowMagnetronWorks.htm a nonsensical relationship; but, somehow jungian.
