EXTRACTION FROM SOLID MATERIALS IN AN ELECTROMAGNETIC FIELD OF SUPERHIGH FREQUENCIES V. V. Beloborodov UDC 665.1.033:54-16:621.3.029.3:538.56 On the basis of the kinetic theory of fluids and the theory of SHF-heating of dielectrics, a theory of extraction is developed and kinetic equations are obtained. The adequacy of the equations is confirmed by experiments. Traditional extraction (without SHF-heating) is a particular case of the general solution. SHF-heating allows one to increase the rate of extraction considerably with a low consumption of energy. JEPTER7492019994 JEPTER749204
