Abstract

This paper examines the transmission behavior of two acoustic metasurfaces and their constituent structural units while including the various material properties that could affect their functionality. The unit cells and the metasurfaces are modeled numerically, and the impact of the structural interaction and thermoviscosity on sound transmission and phase modulation is studied. Each of these effects is viewed individually in order to better understand their influence. Various cases are presented, and the change in the behavior of the metasurfaces is investigated. The deviations from the ideal desired results are examined and highlighted to show that it is important to incorporate these effects to better predict the behavior of acoustic metasurfaces.
