• Description:
  In this paper, a Finite Difference Time Domain (FDTD) - based full wave method is applied to model radio propagation in tunnels. The simulation results based on the FDTD method are compared to ray tracing and modal methods at 455 and 915 MHz for both vertical and horizontal polarizations and show good agreement. It is also shown that the simulation predictions based on all three methods agree well with the results as measured in a real tunnel. [Description provided by NIOSH]
