Description:
Author(s): Li Fan, Wei-wei Yu, Shu-yi Zhang, Hui Zhang, and Jin Ding Zak phases in two types of acoustic metamaterials with negative density or negative modulus are studied. Different from phononic crystals based on Bragg scattering, extraordinary performance in acoustic metamaterials originates from local resonance. We find that the Zak phases in metamaterials are d… [Phys. Rev. B 94, 174307] Published Mon Nov 28, 2016
