Abstract :
This paper presents results showing the accuracy of the ADI technique when used to model the parabolic equation for (a) square (6) circular and (c) semi-circular cylindrical PEC tunnels. For each tunnel, we compare the numerical solution with the known anlytical solution for different descretizations along the transverse plane and propagation axis.
