Acoustic metasurface constructed by periodic parallel Helmholtz resonators for gas sensing applications

Abstract This study investigates a compact acoustic metasurface of periodic parallel Helmholtz resonators with a resonator defect located in the middle of the structure for gas-sensing applications. Introducing defects into the common resonators’ array creates localized resonant modes that affect th...
