Why do TEM modes need two conductors to propagate?

    Why do we need two conducting surfaces to allow TEM modes to propagate through a waveguide? Why can we not propagate TEM waves through a single conducting waveguide?

    With only one conductor, the only solution that satisfies E_tangential at the conductor equal to zero is E=0 everywhere.
