椭圆隧道中UHF电波传播特性

Theory of the Propagation of UHF Radio Waves in Elliptical Tunnels

本文分析了椭圆隧道中UHF电磁波传播的理论、四种波模的截止频率和沿隧道传播的信号强度的衰减率,对衰减率进行了仿真,并将理论结果与实际数据相比较,这些结论有助于设计隧道无线通信系统。

The theoretical study of UHF radio propagation in elliptical tunnels and the cutoff wavelength of four modes, with particular reference to the rate of loss of signal strength along a tunnel, is the concern of this paper, In this paper, the attenuations are simulated, the theoretical results are compared with actual data, the conclusion will gives a reference to design the wireless communication system in tunnels.
