Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as well.

Electromagnetic and acoustic or seismic techniques may provide the significant advantage of a mobile non invasive solution. Surface based sensing of volumetric properties introduces complexity in the form of underdetermined and ill-posed inversion problems. This paper will focus on the forward modeling aspect using COMSOL to the solution of the overall problem.
