Abstract :
Based on the propagation modal and the software simulation method, characteristics of radio wave propagation in rectangular tunnels are studied from the view of the size shift of the tunnel width and height. The results show that the influence of the height change on the vertical polarization mode is greater than on the horizontal polarization mode; that of the width change on the vertical polarization mode is less than on the horizontal polarization mode.
