The terms"acoustic/elastic meta-materials"describe a class of periodic structures with unit cells exhibiting local resonance. This localized resonant structure has been shown to result in negative effective stiffness and/or mass at frequency ranges close to these local resonances. As a result, these structures present unusual wave propagation properties at wavelengths well below the regime corresponding to band-gap generation based on spatial periodicity, (i.e."Bragg scattering"). Therefore… 
In Soil Dynamics, the high ratio of soil substitution by deep foundations or ground reinforcement techniques in urban area, led researchers to believe in a significant impact of these elements on the
