The success in the flexible design of smart acoustic metamaterials is crucially contingent
upon the degree of control over the parameters that uniquely define the spectrum of band …

In this work, a new type of planar square lattice structures for the attenuation of elastic wave
propagation is proposed and designed. To obtain a high vibration attenuation in low …

Acoustic metamaterials allow for creating selective pass-and stop-bands on the frequency
spectrum. We demonstrate the possibility of designing acoustic metamaterials as core-shell …

Mechanical metamaterials and metastructures exhibit superior effective mechanical
properties, such as enhanced energy dissipation and resistance against impact loads …

Introducing multi-resonator microstructure into phononic metamaterials provides more
flexibility in bandgap manipulation. In this work, 3D-acoustic metamaterials of the body-and …

The vibration properties of two-dimensional (2D) finite acoustic metamaterials (AMs)
consisting of discrete masses and springs are investigated in this paper. In order to clarify …

The effect of anisotropic mass density on wave propagation in acoustic/elastic metamaterials
is presented in this research. The use of microstructures to achieve mass anisotropy in …

Metamaterials are generally known for their waves attenuation capabilities. This behaviour,
which is related to the microstructure composing these materials, can be due to a Bragg-type …

Engineering structures for different dispersion and dissipation levels of wave propagation
use internal variable models, which may enhance the performance of acoustic …

Considering the extensive application of periodic structure and bandgap feature of periodic
elastic metamaterial, this paper presents the bandgap mechanism and characteristics of two …
