Microwave heating, variable frequency

The temperature fields induced by microwave heating can be modeled via the simultaneous solution of Maxwell s equations (for the electromagnetic component of the problem) and the heat equation. The modeling is very challenging, in part because the dielectric constants sj. and s" are functions of temperature and the microwave frequency as well as of the microstructural and chemical details of the ceramic [Eq. (lb)]. Also, the thermal conductivity, k (which is needed for the heat transfer calculations), typically is a function of temperature as well as of microstructural variables such as porosity. ...
