Fine manipulation of sound via lossy metamaterials with independent and arbitrary reflection amplitude and phase
The formation of true holograms requires control of both amplitude and phase; however, acoustic metamaterials are generally limited to phase control only. Here, Zhu et al. tailor lossy metamaterials to independently control the amplitude and phase of acoustic wavefronts.
