Effects of Different Parameters on Attenuation Rates in Circular and Arch Tunnels
Radio wave propagation in circular and arch shaped cross-section tunnels is analyzed. The effectrical and mechanical parameters, such as the shape and transverse dimension of the tunnels, frequency, polarization, effectrical parameters like conductivity and permittivity, which have a significant influence on the attenuation inside tunnels are determined. The impact of these parameters on the propagation is analyzed and an optimum set of values is determined. In this paper, taking circular and arch shaped tunnel as an examples, influence of various parameters on UHF radio propagation is analyzed.
