Electromagnetic Model

In order to investigate the law of electromagnetic propagation within microwave heating system, Maxwell's equations are applied to build electromagnetic model of recycled asphalt mixtures. Energy distribution of electromagnetic field in asphalt mixtures is researched based on the Poynting theory. The optimization model of electromagnetic field and structure are established by building relationship between electric field and magnetic field. Experiments of microwave heating allochroic silicagel are performed, which demonstrates the accuracy of electromagnetic field optimization.

Dependent Absorption

The use of microwave heating to initiate combustion synthesis has been increasingly investigated in recent years because of its advantages over traditional methods. A simple mathematical model is used to model these experiments. The microwave power absorption term is modelled as the product of an Arrhenius reaction term with a function that decays exponentially with distance. The former represents the temperature-dependent absorption of the microwaves whereas the latter describes the penetration of the material by the microwaves. Combustion kinetics are modelled as a first-order Arrhenius reaction.
