Principles and Models of Power Density Distribution in Microwave Oven Loads

Multi-mode cavity resonances are generally considered the most important phenomenon in transferring energy to the load in microwave ovens. There are, however, other important phenomena, caused by scattering and near-fields. This paper deals with the mulit-mode resonant and some other important field types. Some main areas where sufficient knowledge is not available are described and the main problems in applying simplified models are discussed.
