dc.description.abstract | The effect of glide-symmetry on the dispersion of acoustic surface waves supported by lines of
open-ended holes in acrylic plates is investigated. Two samples are experimentally characterised,
each formed of a pair of parallel such lines, one having glide-symmetry. This glide-symmetry removes
the condition necessary for the supported ‘even’ and ‘odd’ character acoustic surface waves to form
standing-waves at the first Brillouin zone boundary; there is instead one ‘mixed’ even-odd hybrid
mode. This evolves continuously with increasing frequency to a far greater in-plane wavevector than
possible without the glide condition. This study demonstrates that glide-symmetry opens a new
degree of freedom for the design of acoustic metamaterial devices for the control of acoustic energy
on a surface. | en_GB |
