Do hand carried microwave heaters exist or must the microwaves always be enclosed, as they are in a microwave oven?
My understanding is that there are microwave heating systems that are not enclosed and that are used in medical therapies to provide deep warming to injured tissues in medical patients. But apart from such devices, I've never heard of unenclosed microwave heaters. That's because such heaters would be dangerous, since a user would be exposed to the heating effects of the microwaves. To keep the microwave heating under control, microwave ovens always carefully enclose the microwaves in a metal cooking chamber from which they can't escape.
