摘　　要：为精确地描述矩形空隧道内电磁波传播特性,根据传播理论与几何知识,推导出了矩形隧道中天线安装不同位置下分界点的计算公式;并通过实验验证了天线安装在不同位置下的结果。结果表明:在典型的宽大于高的矩形隧道中,分界点距离主要受天线高度变化而变化,受横向距离影响较小。证明提出的确定隧道电磁波传播分界点的方法是可行的。In order to describe accurately the propagation characteristics of electromagnetic waves in rectangular tunnel,the division point formulas of different antenna positions in rectangular tunnel are deduced according to the propagation theory and geometry knowledge,and the results of different antenna positions are verified by experiments.It is concluded that in a typical rectangular tunnel with the width larger than the height,the division point distance is mainly changed by the height of the antenna,and is less affected by the lateral distance.It is feasible to use the proposed method of this paper to determine the division point of electromagnetic wave propagation in tunnels.
