1. An acoustic metamaterial device, comprising:
fins,
wherein a material for each fin is denser than air to facilitate anisotropic properties of the acoustic metamaterial device,
wherein at least a length dimension and a width dimension for each fin are substantially perpendicular to a direction of sound wave propagation from a sound source, and
wherein each fin along the width dimension and length dimension is sized differently from other fins.
