Two-Dimensional Classical Wave Localization in a Third Sound System
Abstract
Patterned calcium fluoride deposited on glass creates an effective two-dimensional scatterer of third sound propagating on a thin 4He film. We have utilized a substrate with a periodic arrangement of scatterers and a substrate with a random arrangement of scatterers to investigate classical wave propagation and localization using third sound. We observe pass bands on the periodic substrate while only low frequency modes are observed in the disordered case. The presence of high frequency modes on the ordered substrate and the absence of high frequency modes on the disordered substrate indicates we are observing localization on the disordered substrate. We compare the disordered data to the two-dimensional localization theory of Cohen and Machta and find reasonable agreement.
