Abstract

Radio wave propagation in circular and arch shaped cross-section tunnels is analyzed. The electrical and mechanical parameters, such as the shape and transverse dimension of the tunnels, frequency, polarization, electrical 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.
