Abstract
Transmission gaps were found in third-sound waves propagating on a periodic substrate which was a glass plate with aluminum strips arrayed on its surface. Experimental results agreed with Condat and Kirkpatrick's theory [Phys. Rev. B32 (1985) 4392]. Third-sound scattering from a boundary of two different materials were confirmed experimentally for the first time. This will offer a new experimental opportunity to study modern wave phenomena such as "wave localization".
