Abstract
A microwave heating apparatus including a cavity for heating food, a first antenna, which projects into the cavity and is arranged to pass into or through the food in order to irradiate the food internally, and a second antenna arranged to supply microwave radiation into the cavity in order to irradiate the food externally. Microwave energy is supplied to the first and second antennae in such a way that the user can independently control the levels of microwave energy irradiated by the first and second antennae.
