Anomalous wavefront manipulation and broadband sound absorption by metasurfaces with periodic subwavelength modulation
Both periodic subwavelength structures and phase gradient metasurfaces have opened up new degrees of freedom to manipulate the acoustic waves respectively. In this study, a periodic subwavelength structure is introduced into the metasurface to modulate the acoustic surface waves deduced by the phase...
