| 摘 要： | 文章采用表面阻抗法推导了矿井巷道中导行电磁波的单线波模和双线波模特征方程,根据镜像法求得了巷道中任一点的合成场分布,求解了圆形巷道中的单线波模衰减常数,并对分析结果进行了数值分析.仿真结果表明:导线的存在使低频单线波模的传输衰减随频率的增加而增大,当导线靠近巷道壁时,趋肤效应越严重,衰减越严重；当导线悬挂于巷道中央时,...

| Abstract: | The equations of both monofilar mode and bifilar mode of guided electromagnetic waves in mine tunnels are presented by using surface impedance method,and the distribution of synthesized electromagnetic field of a casual point in tunnels is given by utilizing image approach.The attenuation constant of monofilar mode in a circular tunnel is solved.The numerical simulation is carried out and the results show that the transmission attenuation of low frequency monofilar mode increases with the increasing frequen... |
