Mode conversion can occur if two (or more) solutions of the dispersion equation coalesce. If the corresponding polarization vectors do not coincide (e.g., in lossless media) and the group velocities are finite and parallel, a coupled system of transport equations is derived for the amplitudes of the coinciding modes, valid in a small “conversion region.”
