    Notes: We analyzed the wave propagation characteristics of the crossroad inside a tunnel, using the boundary-element method. To simplify, the tunnel structure is assumed to be two-dimensional and the side walls to be lossy dielectrics. We could improve the radio communication characteristics between two cross tunnels by a tetragonal reflector placed at the center of the crossroad. The diagonal length of the proper reflector is about 10%–20% of the tunnel width.
