Implementation of dispersion-free slow acoustic wave propagation and phase engineering with helical-structured metamaterials
There is great interest in slow wave propagation for a variety of applications. Here, Zhu et al. present a dispersion-free helical-structured metamaterial that implements acoustic wave deceleration at broad bandwidth and demonstrates specially designed phase modulation to incident sound through heli...
