摘要
单模腔是国际上较为流行的微波烧结结构的加热腔,具有功率密度高、损耗小、温度均匀和易于控制等优点.在单模腔的设计中,由于负载的特性对单模腔中场分布具有较大的影响,因此是设计单模腔的重要参考.首先通过波导理论推导了单模谐振腔中的电磁场分布,其次探讨了单模腔在负载和空载情况下场分布的情况以及反射系数随着耦合孔变化的影响,并且对负载时耦合孔的大小进行了优化,最后分析了有载单模反应腔的负载特性的变化对场分布的影响.仿真优化的结果证明了负载特性的变化对场分布的影响,为单模腔体的设计提供参考依据.
The single mode microwave cavity becomes the main microwave heating sinter cavity internationally because of its high power density, low loss, uniformity temperature and easy control. As an important factor in cavity design, the load properties have great impact on the electric field in single mode microwave cavity. In this paper, the electric field in single mode microwave cavity is firstly obtaine^t according to the waveguide theorem. The electric field and reflection coefficient in single mode microwave on load and no load are discussed. Besides, the size of coupling aperture is optimized. Finally, the effect of load variance on the single mode microwave on load is analyzed. This paper can provide references to single mode cavity design.
