Which device heats food primarily by microwave radiation?

Microwave heating works by using microwave radiation to excite water and other polar molecules inside food. The microwaves cause these molecules to rotate rapidly, and that motion turns into heat inside the food itself. The device that does this primarily is the microwave oven, because it generates microwaves with a magnetron and the energy is deposited mainly inside the food rather than from hot surfaces or surrounding air. Other appliances heat food mainly through radiant heat from hot elements, hot air convection, or steam transfer, not by microwave radiation. So the one that heats food primarily by microwave radiation is the microwave oven.
