Abstract

We theoretically analyze and numerically demonstrate that guided-mode resonance (GMR) effects can be achieved in acoustic systems. Similar to its optical counterpart, the acoustic GMR-like effects can support multiple narrow bandwidth transmission dips at a broad range of frequencies and give rise to strongly localized acoustic pressure fields in the acoustic waveguide layer. The discussed fundamental phenomena will allow a broad range of applications, including the design of filters, sensors, and other novel acoustic devices.
