Resumen:
The propagation of third sound on a one-dimensional periodic substrate is studied for the case when the helium film is subjected to a uniform flow field. The modifications introduced by the flow in the band structure depend on the relative directions of the flow and the wave propagation. A simple derivation of the effects of the flow on the location of the transmission resonances corresponding to a disordered substrate is also presented. These results are relevant to the problem of third-sound Anderson localization.
