基于矩形直巷道波模传输特性和弯曲隧道拐角射线路径分析
对矩形弯曲隧道中天线不同极化、不同发射频率对电磁波传播的影响进行理论分析
并通过实验验证得出结论:当隧道宽大于高时
水平极化电磁波受发射频率影响较大
频率较低时
水平极化优于垂直极化;频率增大
垂直极化优于水平极化;当发射频率大于某个数值时
极化方式影响的区别逐渐减弱。当宽小于高时
垂直极化优于水平极化
垂直极化电磁波更适合传播
对实际矩形弯曲隧道中
收发天线极化方式和发射频率的选择具有指导意义。
Based on wave mode transmission characteristics in straight rectangular tunnel and corner ray path analysis in curved tunnel
influence of antenna different polarization mode under different transmission frequencies in rectangular curved tunnel on electromagnetic wave propagation characteristics is analyzed in theory
and the correctness of the theory is verified by experiment
the conclusion is drawn that when the width of tunnel is greater than its height
the transmitting frequency has a great influence on horizontal polarization electromagnetic wave
when transmitting frequency is low
horizontal polarization mode is better than vertical polarization mode; while transmission frequencis increasing
the vertical polarization mode is better than horizontal polarization mode; When the transmission frequency is greater than a certain value
the influence of different polarization modes are weakened gradually.When the width is less than the height
the vertical polarization mode is better than horizontal polarization mode
vertical polarization electromagnetic wave is more suitable for propagation.These have a guiding significance on choice of transmitting and receiving antenna polarization mode and transmission frequency in the actual rectangular curved tunnel.
