摘要
文中通过HFSS电磁仿真软件,设计一种新型微波谐振腔,通过仿真分析,比较了双馈口的不同排列方式对腔体耦合和反射的影响,并且结合加入不同的负载,验证了馈口的高度决定了馈口及馈口间的反射功率,最后通过优化高度,得出了负载对微波的吸收效率,验证了该新型微波谐振腔设计的合理性。
A new type of microwave cavity is designed by using HFSS electromagnetic simulation software.Through simulation analysis,the effects of different arrangement of doubly-fed ports on cavity coupling and reflection are compared,and a load is added to verify the simulation.The height of the feed port determines the reflected powers of and between the feed ports.By optimizing the height,the microwave absorption efficiency of the load is obtained,and the design rationality of the new microwave cavity is verified.
