Some properties of electromagnetic metamaterials have been translated, using some wave analogies, to surface seismic wave control in sedimentary soils structured at the meter scale. Two large scale experiments performed in 2012 near the French cities of Grenoble [Brule et al., PRL 112, 133901, 2014] and Lyon [Brule et al., Sci. Rep. 7, 18066, 2017] have confirmed the usefulness of this methodology and its potential influence on soil-structure interaction. We present here a new perspective on…

The influence of structure geometry and material on seismic metamaterial performance

This study investigates altering the structure geometries of SMs with the aim of creating large bandgaps, and shows that square stiff inclusions, perform better in comparison to circular ones, whilst keeping the same filling fraction.

The Influence of Clamping, Structure Geometry, and Material on Seismic Metamaterial Performance

Diverting and controlling the impact of elastic vibrations upon an infrastructure is a major challenge for seismic hazard mitigation and for the reduction of machine noise and vehicle vibration in



Experiments on seismic metamaterials: molding surface waves.

For complex natural materials such as soils, this large-scale experiment was needed to show the practical feasibility of seismic metamaterials and to stress their importance for applications in civil engineering.

Auxetic-like metamaterials as novel earthquake protections

We propose that wave propagation through a class of mechanical metamaterials opens unprecedented avenues in seismic wave protection based on spectral properties of auxetic-like metamaterials. The

The influence of building interactions on seismic and elastic body waves

We outline some recent research advances on the control of elastic waves in thin and thick plates, that have occurred since the large scale experiment [S. Brûlé, Phys. Rev. Lett. 112, 133901 (2014)]

Experimental evidence of auxetic features in seismic metamaterials: Ellipticity of seismic Rayleigh waves for subsurface architectured ground with holes

Structured soils with regular meshes of metric size holes implemented in first ten meters of the ground have been theoretically and experimentally tested under seismic disturbance this last decade.

Control of Rayleigh-like waves in thick plate Willis metamaterials

Recent advances in control of anthropic seismic sources in structured soil led us to explore interactions of elastic waves propagating in plates (with soil parameters) structured with concrete

Metamaterial-like transformed urbanism

Viewed from the sky, the urban fabric pattern appears similar to the geometry of structured devices called metamaterials; these were developed by Physicists to interact with waves that have

Role of nanophotonics in the birth of seismic megastructures

Abstract The discovery of photonic crystals 30 years ago in conjunction with research advances in plasmonics and metamaterials, has inspired the concept of decameter scale metasurfaces, coined

A seismic metamaterial: The resonant metawedge

The efficiency of the resonant metawedge shows that large-scale mechanical metamaterials are feasible, will have application, and that the time is ripe for considering many optical devices in the seismic and geophysical context.

Assessment of the Urbanization Effect on Seismic Response

This article introduces two analytical methods that aim at investigating the effect of the urban environment on seismic motions. We regard cities as a periodic distribution of simple oscillators. The
