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 ...

MIT engineers have devised a new, non-invasive way to monitor the stiffness of single living cells, using acoustic waves. Their technique could be used to study many biological phenomena, such as ...
