Abstract A three-dimensional finite element method is developed to simulate the microwave field structure and power distribution dissipated in the dielectric material in a cavity which may contain lossy, inhomo- geneous and isotropic materials of arbitrary shape. The method was tested first by analyzing a simple problem which has an analytical solution. For the material studied in this work with microwaves at a frequency of 2.45 GHz, it was concluded that if the mesh size of the element in the direction of wave propagation is less than 1.5 cm good agreement can be achieved between the numerical and exact solutions. Then the microwave power distribution in a multimode rectangular cavity with lossy material is investigated. The cavity is excited by a rectangular waveguide at the frequency of 2.45 GHz.
