  Abstract:  Microwaves are, maybe, one of the greatest discoveries of the 20’th century. With a vavelenght between 30 cm and 3 mm and a power between 1 mW and 500 KW they are used practically in all fields from medicine to industry. Microwave thermal and chemical tratments are well known for his high efficiency, 3 to 1000 times greater then the conventional processes because of the direct energy transfer into materials and the selective compounds heating following dielectric permittivity parameters of the materials involved in reaction or in the treatment (equation 1):
