Theoretical aspects of microwave dielectric heating

Microwave radiation - frequencies available for dielectric heating 

The microwave region of the electromagnetic spectrum corresponds to wavelengths of 1 cm to 1 m (30 GHz to 300 MHz). The wavelengths of 1-25 cm are also used extensively 

The interactions of microwave radiation with chemicals may be interpreted in a manner which chemists will be more familiar with or more traditionally from a physics standpoint. Both interpretations are summarised below10  

In summary, it is important to emphasise that microwave dielectric heating is not a quantum mechanical phenomenon localised at one molecular centre, but is a collective property that occurs in a semi-classical maimer and involves aggregates of molecules. Energy transfer is rapid between these molecules and this limits the extent of localisation of the heating.
