On enhancing the noise-reduction performance of the acoustic lined duct utilizing the phase-modulating metasurface
Abstract This work proposes a noise-reduction structure that integrates phase-modulating metasurface (PMM) with acoustic liners (ALs) to enhance the narrow band absorption performance of a duct with relatively small length-diameter ratio. The PMM manipulates the wavefront by introducing different tr...
