矩形隧道中的金属支护立柱对电磁波截止频率的影响
2.
The effect of metallic pit prop on transmission characteristics in tunnel is studied.
针对矩形巷道中由于金属支护立柱的存在而带来的分叉不连续问题,提出用分叉波导模型并用模式匹配法和多模传输理论分析传输特性。
3.
Using finite-element method the effects of long objects, such as cage, train and metal pit prop, on electromagnetic wave cutoff frequency is researched systematically in regular tunnels, and it is shown that the long metal objects lower TE wave cutoff frequency and raise TM wave cutoff frequency.
利用有限元方法系统地研究了机车、罐笼、金属支护立柱等长列金属物体对井下规则隧道中电磁波截止频率的影响,可知长列金属物体的存在使TE波模截止频率降低,而使TM波模截止频率升高。
补充资料：支柱
①起支撑作用的柱子。比喻中坚力量：国家的支柱｜他是厂里的主要支柱。②撑起；撑住：这种局面他能支柱多久?
