I want to confirm that the TEM wave is actually travel inside the dielectric between the two plates of the parallel plate transmission line. So even though surface current and surface charge appeared on the surface of the conductor plates as the consequence of the boundary conditions between the dielectric and conductor boundries, the TEM wave traveling in the dielectric between the plates are still consider as "source free" where
