Ultra-low and ultra-broad-band nonlinear acoustic metamaterials.
TL;DR: Fang et al. fabricate one- and two-dimensional nonlinear acoustic metamaterials with a broadband, low-frequency, response—greatly suppressing low frequency noise.
Tunable waveguide and cavity in a phononic crystal plate by controlling whispering-gallery modes in hollow pillars

TL;DR: In this paper, the authors investigate the properties of a phononic crystal plate with hollow pillars and introduce the existence of whisperinggallery modes (WGMs) that can merge inside both Bragg and low frequency band gaps.
Robust Fano resonance in a topological mechanical beam
TL;DR: In this article, a robust Fano mechanical resonance with topological protection was achieved by engineering band inversion of two different vibrating symmetries of a pillared beam that gives rise to dark and bright edge modes.
Propagation of guided elastic waves in 2D phononic crystals.
TL;DR: It is shown that, for any guided elastic wave, Lamb or generalised Lamb modes, stop bands appear in the dispersion curves, displaying a phononic band structure in both cases.

Negative effective mass density of acoustic metamaterial plate decorated with low frequency resonant pillars
TL;DR: In this paper, the elastic wave dispersion by a phononic metamaterial plate containing low frequency resonator stubs arranged periodically over the plate was investigated, and it was shown that this system not only provides stop bands for wavelengths much larger than the periodicity but also displays negative behavior of its effective mass density under the homogenization assumption.
