Microwave heating is an important process for many commercial, industrial and household applications. In microwave heating applications, the energy is introduced directly into the volume of the material. As a consequence the quality of the process is highly dependent on the uniformity of the electromagnetic field distribution.

Thus, developing a uniform electromagnetic field inside the cavities represents a crucial challenge to avoid localized overheating. To better understand the complexity of the problem, and enhance the design of microwave processing technology, microwave processing has been analyzed using COMSOL Multiphysics.
