Effects of sample's dielectric property on the performance of microwave heating

The performance of microwave heating depends on its operating frequency, applied power, sample's dielectric property, geometry, thickness, position of the sample placed in the multimode applicator and the size of applicator. This paper presents the effects of dielectric properties of the clay sample placed inside the multimode applicator on the performance of microwave heating. COMSOL Multiphysics software was used to simulate and estimate the electric field distribution over the surface of the sample for two different dielectric properties of clay sample. The simulated and experimentally obtained results are almost matched.
