Modeling radio wave propagation in tunnels with a vectorial parabolic equation.

Modeling radio wave propagation in tunnels with a vectorial parabolic equation.

To study radio wave propagation in tunnels, we present a vectorial parabolic equation (PE) taking into account the cross-section shape, wall impedances, slowly varying curvature, and torsion of the tunnel axis. For rectangular cross section, two polarizations are decoupled and two families of adiaba...
