Homogeneous dielectrics dispersion energies

The fact that different chemical species absorb microwave energy to a different extent implies that the thermal energy so-produced and imparted to the surrounding environment will also vary with the chemical species. Hence, for systems that possess inherent non-homogeneous structural characteristics, or that contain different chemical species with different dielectric properties dispersed into a homogeneous environment, it is possible to effect a selective heating of some areas, or components of the systems.
