Built-up structural steel sections as seismic metamaterials for surface wave attenuation with low frequency wide bandgap in layered soil medium
Muhammad,C.W. Lim,J. N. Reddy +2 more
TL;DR: In this article, the propagation of surface waves through periodically arranged built-up steel section (resonator) in single and multiple layered soil medium (substrate) and to study the feasibility of surface wave attenuation by finite element technique are taken into consideration.

Low-frequency elastic wave attenuation in a composite acoustic black hole beam
TL;DR: In this article, a composite acoustic black hole (ABH) beam structure with low-frequency flexural wave attenuation properties was proposed. But the composite beam structure does not reveal the necessary low local stiffness or high stress concentration, and vibration modes indicate that flexural attenuation still depends on the ABH.

Experimental demonstration of a dissipative multi-resonator metamaterial for broadband elastic wave attenuation
TL;DR: In this article, a dissipative EMM with multiple resonators comprised from layered spherical inclusions embedded in an epoxy matrix is proposed for attenuation of elastic wave energy spanning broad frequency spectrums.

Tunable bandgaps in soft phononic plates with spring-mass-like resonators
TL;DR: In this article, a phononic crystal plate made of soft material with resonant units is proposed, where each resonant unit consists of a mass which is connected to the perforated plate by thin beams.

Double-negative acoustic metamaterial.
TL;DR: The existence of acoustic metamaterial, in which both the effective density and bulk modulus are simultaneously negative, in the true and strict sense of an effective medium, is shown.

Negative Refractive Index in Chiral Metamaterials
TL;DR: The presence of strong chirality in the terahertz metamaterial lifts the degeneracy for the two circularly polarized waves and allows for the achievement of negative refractive index without requiring simultaneously negative permittivity and negative permeability.
