Abstract

Ten years ago, two large scale experiments on seismic metamaterials demonstrated a cloaking effect for surface Rayleigh waves generated by a time-harmonic source at 50 Hertz in a sedimentary soil structured with boreholes 0.3m in diameter [1] and a lensing effect via negative refraction at 10 Hertz for surface Rayleigh waves generated by a multi-frequency source in a sedimentary soil structured with boreholes 2m in diameter [2]. These experiments have fueled the interest in large scale mechanical metamaterials for applications in civil engineering. Here, we propose that some experiments on broadband cloaking of spoof plasmon polaritons on metal surfaces structured with TiO2 [3] could be translated to the realm of seismic metamaterials. We point out that drawing analogies between surface Rayleigh waves in geophysics and spoof plasmon polariton in plasmonics, makes it possible to envision seismic cloaks and carpets at the decameter and kilometer scales. Research advances in photonics and plasmonics in the past twenty years might lead to a paradigm shift in earthquake engineering in the near future.
