A New Model for Predicting the Characteristic of RF Propagation in Rectangular Tunnel
This paper presents a new model based on thegeometrical-optical theory and the uniform theory of diffraction(GO-UTD) for predicting the characteristic of RF propagationin rectangular tunnel.It transforms three-dimensional (3D)propagation model of radio signal in tunnel to two-dimensional(2D) propagation model,which could be easily tackled.Simulation results compared with another prediction model(Wireless Insite) show that this model can accurately predictthe narrow band propagation characteristic of radio signal inrectangular tunnel.Moreover,it reduces the computationalcomplexity greatly and improves the efficiency of prediction.
