Effects of the metallic pit prop on the electromagnetic wave cutoff frequency in the rectangular tunnel;

矩形隧道中的金屬支護立柱對電磁波截止頻率的影響

The effect of metallic pit prop on transmission characteristics in tunnel is studied.

針對矩形巷道中由于金屬支護立柱的存在而帶來的分叉不連續問題,提出用分叉波導模型并用模式匹配法和多模傳輸理論分析傳輸特性。

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.

利用有限元方法系統地研究了機車、罐籠、金屬支護立柱等長列金屬物體對井下規則隧道中電磁波截止頻率的影響,可知長列金屬物體的存在使TE波模截止頻率降低,而使TM波模截止頻率升高。
