A chiral elastic metamaterial beam for broadband vibration suppression (2014, positive): “The unusual low-frequency bandgap in such composite was explained by the negative effective mass density through equivalent discrete mass-spring systems [2] [3] [4] [5].”
Theory of Metamaterial Beams for Broadband Vibration Absorption (2010, background): “In the literature, only few simple models for bar-like acoustic metamaterials were proposed, and they are all based on spatial averaging of heterogeneous material properties and hence are valid only for waves of wavelengths much longer than the sizes of subunits (Li and Chan, 2004; Milton and Willis”

Metadamping: An emergent phenomenon in dissipative metamaterials (2012, methodology): “By considering lumped masses, springs, and viscous damping (dashpot) elements, we construct a simple 1D model of a damped diatomic AM (represented by a “mass-in-mass” configuration [7] as shown in Fig.”
Design of tunable acoustic metamaterials through periodic arrays of resonant shunted piezos (2011, background): “The resonant behavior of the shunts is reflected in the equivalent mechanical behavior of the waveguide, which is a behavior observed for other internally resonating metamaterials and has been interpreted as the result of an apparent negative stiffness at the internal resonance (Huang et al 2009).”
Tailoring vibration suppression bands with hierarchical metamaterials containing local resonators (2019, neutral): “system that has been extensively studied [14] as shown in Fig.”
