Several techniques can be used to study electromagnetic propagation in tunnels. A
combination of two of such techniques is presented in this paper to model propagation
inside a rectangular tunnel. They are combined in order to maximize the benefits inherent to their theoretical principles and restrictions. Fields in the region close to the transmitter are obtained by means of spectral theory ,, whereas in the far field the parabolic regimen is used ,.
