Perfect and broadband acoustic absorption by critically coupled sub-wavelength resonators
Perfect absorption is an interdisciplinary topic with a large number of applications, the challenge of which consists of broadening its inherently narrow frequency-band performance. We experimentally and analytically report perfect and broadband absorption for audible sound, by the mechanism of crit...
