Observation of acoustic Dirac-like cone and double zero refractive index
Impedance mismatch between acoustic metamaterials and a surrounding medium hinders efficient applications, especially for zero-index materials. Here, Duboiset al. utilize the Dirac-like dispersion in a double-zero-index material to overcome this problem and to collimate sound.
