Abstract
We report preliminary measurements of the propagation of third sound for 4He adsorbed on substrates which incorporate periodic and random arrays of one-dimensional scatterers. Qualitative predictions for the band structure of the periodic system and for classical localization in the disordered system will be compared to the data.Keywords
