摘　　要：介绍了用于太赫兹分子钟的精细低损耗密闭结构太赫兹腔体的设计方法及解决思路,利用CST对太赫兹腔体开展了物理仿真设计及结构设计,通过仿真优化设计出230 GHz±10 GHz范围内,反射系数S_(11)小于-10 dB的小型化太赫兹腔体结构。利用现有的加工技术完成了太赫兹腔体的加工与制备,并开展了冷测工作,实现带内反射小于-10 dB,传输损耗低于-5 dB,为后续的太赫兹分子钟的研制奠定了基础。A design method and experimental results of the low loss terahertz cavity used in terahertz molecular clock are introduced.Physical simulation design and structure design of terahertz cavity are carried out by CST.Through simulation and optimization,the miniaturized terahertz cavity structure with the reflection coefficient S_(11) less than-10 dB is designed in the range of 230 GHz±10 GHz.The fabrication of terahertz cavity is completed by using the existing processing technology.The reflection of the cavity in G band is less than-10 dB and the transmission loss is less than-5 dB,which lays the foundation for the development of terahertz molecular clock.
