AB  - The high density of deep foundation or ground reinforcement techniques in urban area, leads researchers to believe in a significant interaction of these buried structures with a certain component of the seismic signal. A promising way to cause a modification on the seismic disturbance is to create a complete dynamic artificial anisotropy by implementing geometrical elements, full or empty, in the soil. The physical process is the interference of waves (body or surface waves) scattered from surfaces or objects. The effects of the dynamic anisotropy are reinforced by the local resonance of implemented, which are disposed along a grid according to transformation elastodynamics and morphing tools that could theoretically lead to an ideal cloak detouring waves around a protected area. In this periodic or non-periodic media, the desired effects are total reflection (Bragg's effect), band-gaps, wave-path control, attenuation by energy-dissipation, etc.
