Microwave Mapper

 A microwave detecting sheet

Ever nuke something, only to have it hot on one end but cold on the other? Yes, despite modern waveguides, stirrer blades, rotating antennae and carousels modern microwaves can still be a hit-or-miss proposition.

Enter the Microwave Mapper, a large, thin sheet of neoprene-like material which can be cut to fit the floor of your microwave.

When exposed to high-intensity microwaves, chemicals in the Microwave Mapper change color, indicating the strength of exposure for that particular spot. Alternating layers of the mat and plates or bowls in your microwave will give you a three dimensional picture of microwave strength in your oven.

The Microwave Mapper works equally well on carousel-ed microwaves, too. Just make sure you cut the mat into a circle small enough to spin inside the microwave.

Use the distance between the hot spots... http://www.physics....rs/n34/marshmal.htm

       And then what? Only cook foods in the shape of the map formations?

       Then you mount a complex computer-controlled multiple axis carousel mechanism inside the oven. You use the mapped pattern to program this mechanism. Then it can move the food through complex (and possibly entertaining) gyrations to make sure it gets absolutely even heating.   

       It'll probably only quadruple the cost of the oven, but thats progress for you! ;-)

       Alternatively if there was a way to randomize the outflow of micro waves you wouldn't need to move the food at all. Maybe more than one source of power... am I making any sense? Small appliances aren't my forte, but this is a problem that deserves a solution.

       [krelnik] Not at all, you simply place your dishes over the "hot spots".
—phoenix, Oct 08 2003
   

       According to the first link, the hot spots are about 6 cm apart. If your dish is much larger than that (and most are) you are still gonna have uneven heating over short periods.
