The manufacturers rating of the power output of a domestic oven is based on the power delivered to a specified load of water. In fact, the power dissipated in a load can vary considerably with, for example, the mass, the shape or the location of the load. The authors use an enhanced version of the finite difference time domain (FDTD) method to investigate how the power absorbed by the workloads changes with these factors. In microwave heating and drying it is also important to know the field and the temperature distribution in the heated objects. They investigate how the distribution changes when the frequency of the source changes.
