The solid state radio frequency (RF) technology provides much more precision and control over the radio wave energy being emitted than a traditional microwave. Not only does that enable food to be cooked faster, but it also makes it possible to treat different foods in different ways, all at the same time.

In other words, a RF oven would allow you to cook a whole meal at once, with amplifiers sending out one radio beam set to cook meat, another to take care of vegetables and a third to bake a dinner roll.
