摘要

In this paper, the coaxial cavity is used to study the interaction mechanism between the material and the strong microwave electric field, through the establishment of re-entrant coaxial resonant cavity model, analyze the principle of different coupling modes and comparison, the most used to feed the cavity using hole coupling. Subsequent experiments based on the re-entrant coaxial resonant cavity, the results show that the microwave action at the beginning of the non-thermal consequences, with the increase of the action time, the thermal consequences is gradually obvious, for the high-power microwave material properties characterization and testing provides a new method and insights.
