A model is described for predicting temperature profiles in materials heated by microwave power at 2450 MHz and 915 MHz. Theoretical and some experimental data are given to show that internal temperatures in cylinders and spheres exposed to microwaves from all sides are considerably higher than the surface temperatures of the materials. The time dependent three-dimensional heat conduction equation including an internal heat generation term is solved for parallel slabs and infinite cylinders.
