ABSTRACT
A domestic microwave oven is a multimode cavity in which electromagnetic waves form a resonant pattern. When food is present inside the oven, the energy of the electromagnetic waves is transferred to the water molecules, ions, and other food components, raising the food temperature. Figure 1 shows a typical domestic microwave oven with various components. For a detailed discussion on the physical components of a microwave system, see Chapter 7 and references such as Ref. 1.
