I think that's what Goji is doing with these power transistors. Go to the Freescale site in the Electronic Design article, or go here: http://www.gojifoodsolutions.com/ http://www.gojifoodsolutions.com/ Their claim is that they cook food more rapidly and uniformly (no hot spots). The site says little about how the tech works, but guessing, I think their oven beam-forms and scans the food. By looking at the reflected power as a function of the scan position, you should be able to calculate the spatial power absorption profile of the food. That would let you control beam geometry and power to eliminate hot spots. Would be fun to try an oven that has this tech. Beam forming at microwave frequencies has been common in military systems for decades, but I didn't think I'd see it get cheap enough to use in my kitchen in my lifetime. Yum! Now about that poached salmon...
