摘要
本文从理论上分析了以长天线为导波系统，在隧道内进行移动通信的可行性。并对该系统中电磁波沿隧道纵向传播过程的衰减情况、衰减与频率的关系作了具体的分析计算。
The guiding wave system constructed with the Iong antenna used for propagating of the guiding traveling wave in the tunnel has been theoretically analysed in the paper.The attenuation and the relationship between the attenuation and the frepuency of the electromagnetic wave which propagates along the tunnel were calculated as well.
