Abstract: The emergency of anisotropic acoustic metamaterials provides great opportunity for controlling acoustic propagations and realizes many exotic acoustic phenomena. However, the realization of enhanced directional propagation with an unchanged wavefront based on anisotropic metamaterials remains… read more here.
