title = "Modeling sound transmission through a periodic acoustic metamaterial grating of finite size",
abstract = "Recent studies have discovered that acoustic metamaterial possesses great versatility in designing novel acoustic systems. This study investigates into the sound transmission through a periodic acoustic metamaterial grating of finite size. The single-layer grating is constructed by periodically arranging sub-wavelength unit cells in a slab, as a part of a large baffle between two acoustic domains. The metamaterial unit cell consists of an open duct decorated with coiled resonators, which intends to suppress sound transmission using its acoustic stop-band. The space-coiling structure allows the metamaterial to operate at low frequency with a compact size. Analytical approach to predict the sound transmission loss (STL) of the combined baffle is developed. The concept of metamaterial grating can be applied to the design of a novel ventilation window system with improved noise insulation.",
