A dielectric material can be processed with energy in the form of high-frequency electromagnetic waves. The principal frequencies of microwave heating are between 900 and 2 450 MHz. At lower microwave frequencies, conductive currents flowing within the material due to the movement of ionic constituents can
transfer energy from the microwave field to the material. At higher frequencies, the energy absorption is primarily due to molecules with permanent dipole, which tend to re-orientate under the influence of a microwave electric field. This re-orientation loss mechanism originates from the inability of the polarisation to follow extremely rapid reversals of the electric field, so the polarisation phasor lags the applied
electric field. This ensures that the resulting current density has a component in phase with the field, and therefore power is dissipated in the dielectric material.
