Abstract: Acoustic surface waves (ASWs) can be generated through a one-dimensional array of grooves. Sound can be collimated by ASWs. However, in previous studies, the groove period and grating period have been the same. In this… read more here.

Abstract: We design, simulate, and experimentally characterize an acoustic metasurface comprising of a 1D array of open, sound-hard, cavities, modulated with beyond-nearest-neighbor (BNN) couplings in the form of additional connecting cavities embedded beneath the surface. The… read more here.
