Abstract :
A new technique is applied to the modelization of radio waves propagation in mine tunnel having lossy dielectric side walls of random roughness. The resultant model takes into account the spatial variability of the electromagnetic waves in non canonical rough mine tunnels and makes use of the cascade impedance method (CIM) to predict the propagation behavior. Two (2-D) and three dimensional (3-D) propagation models were obtained and compared with experimental data.
