Acoustic metamaterial beams based on multi-frequency vibration absorbers
TLDR
In this paper, the authors proposed a new metamaterial beam based on multi-frequency vibration absorbers for broadband vibration absorption, which consists of a uniform isotropic beam and small two-mass spring-mass-damper subsystems at many locations along the beam.About:

Wave propagation in metamaterial plates with periodic local resonances
TL;DR: In this article, a finite element model (FEM) is developed to predict the modal and frequency response of different configurations of the metamaterial plates and a Floquet-Bloch approach is exercised to demonstrate the stop band and mechanical filtering capabilities over a broad range of frequencies.
