Abstract
In microwave heating, the spatial relationship between the microwave mode and the internal structure has an important meaning. Using the microwave of TE_<10> mode and frequency of 2.45GHz in rectangular waveguide, we have investigated the effect of the internal structure of the sample on the characteristics of microwave heating, and have indicated the guideline for the optimization of microwave heating by controlling reflected and transmitted waves. It was found that the characteristics of microwave heating in the in-series structure which installed the air layer in the high dielectric object strongly depend on the thickness and the setting position of the air layer.
