Abstract :
The paper mainly focuses on the characteristics of millimeter wave propagation at 38 GHz in circular subway tunnels. Ray tracing method is implemented to evaluate the path loss in the tunnels. The proposed simulation based on ray tracing method has been validated by comparing results with measurements obtained in No.9 subway tunnel of Shanghai. Further simulations both in straight and curved tunnels have been carried out to comprehend the characteristics of millimeter wave propagation at 38 GHz in circular subway tunnels.
