N2 - We introduce the concept of localized acoustic surface
modes (ASMs). We demonstrate that they are induced on a
two-dimensional cylindrical rigid surface with
subwavelength corrugations under excitation by an incident
acoustic plane wave. Our results show that the corrugated
rigid surface is acoustically equivalent to a cylindrical
scatterer with uniform mass density that can be represented
using a Drude-like model. This, indeed, suggests that
plasmonic-like acoustic materials can be engineered with
potential applications in various areas including sensing,
imaging, and cloaking.
