Speaker: S.Guenneau (Aix-Marseille Universit\'e, Institut Fresnel)
Abstract: In the past few years, experiments on control of Lamb waves
in plates have conclusively shown the possibility to achieve a flat
lens, Maxwell's fisheye and an invisibility cloak over a range of KHz
frequencies. Using analogies between flexural waves in structured
plates and Rayleigh waves in structured soils, scientists at the
Fresnel Institute of Aix-Marseille University and Menard's civil
engineering company have designed and experimentally demonstrated that
cloaking and lensing can be achieved for seismic waves around 10 Hz.
Seismic metamaterials might pave the way towards a new generation of
passive earthquake protection..
