Heating mechanism of reactive system under microwave irradiation is computationally studied. TE10 incident wave (2.45GHz and 500W) through a rectangular waveguide and a one step global reaction, A+B=>C, are considered here. It is assumed that the reactants A and B have a complex permittivity and the product C has only real part of permittivity. The governing equations are solved by using COMSOL Multiphysics. As a result, rapid change of temperature was reproduced.
