Wave propagation through a structured medium has attracted the attention of researchers for
centuries due to its relevance to problems in condensed matter physics, chemistry, optics …

The purpose of this study is to investigate surface-wave isolation by periodic piles from the
perspective of attenuation zones. There are three major components. The first is the …

The article analyses two potential metamaterial designs, the metafoundation and the
metabarrier, capable to attenuate seismic waves impact on buildings or structural …

A comprehensive numerical study on the performance of a novel nonlinear foundation
consisting of alternating layers of lead rubber bearings and concrete slabs is presented in …

A band gap region, or simply a band gap, is a range of frequencies where vibrations of
certain frequency ranges are isolated. In the present paper, such ranges are sought through …

A partially embedded gradient metabarrier (PEGM) for seismic Rayleigh waves was
designed and studied using the finite-element method (FEM). Investigations on the partially …

In this study, a triangular array of cylindrical holes was shown to function as a local resonator
to seismic metamaterials against the vibration generator loading in the geophysics concept …

Metamaterials, which draw their origin from a special class of structured (periodic) materials
characterized by a dynamic filtering effect, have recently emerged as a prospective means …

A novel device, called Vibrating Barrier (ViBa), that aims to reduce the vibrations of adjacent
structures subjected to ground motion waves has been recently proposed. The ViBa is a …

The principle of influencing oscillation amplitudes of a primary system via secondary
attachments can be enhanced with inclusion of nonlinear mechanisms towards energy …
