Abstract

Employing third sound in a superfluid helium film as an acoustic wave, transmission spectra are measured experimentally in the Penrose lattice. The spectra are extremely sensitive to the impinging direction of third sound. The transmissivity is suppressed strongly at certain frequency ranges. A transparent direction of the Penrose lattice is found simultaneously. We attribute the origin of the prominent suppressions of transmissivity to the multiple diffraction of third sound in the Penrose lattice.
