An acoustic metaliner for ultra-broadband sound absorption

Emerging artificial acoustically soft boundaries (ASBs) have shown great potential for developing compact sound absorptive devices with excellent ventilation performance. However, current realizations of ASBs suffer from narrow-band limitations, which necessitate a stringent matching of resonant cha...
