A discrete approach for modelling the EM wave attenuation in tunnels

The purpose of this study is to develop a new model to analyze the attenuation of EM waves in tunnel environments, using the scattering properties of discrete thin curved surfaces. There are various models in literature that are developed to calculate attenuation in tunnels. In this paper a new model will be introduced. The simulation results would compare to the simulation results of the previously published models along with the results of various measurements.
