Materials engineered at the micro- and nano-meter scale have had a tremendous lasting impact in photonics phononics, with applications ranging from periodic structures disallowing light sound propagation stop band frequencies, to subwavelength focussing cloaking metamaterials. Here, we present description of seismic test held on soil structured meter using vibrocompaction probes. The most simplistic way interact wave is modify global properties medium, acting density then velocity. main concept reduce amplification waves free surface, called site effects earthquake engineering. However, an alternative counteract signal by modifying distribution energy thanks metamaterial made grid vertical, cylindrical empty inclusions bored initial soil, agreement numerical simulations approximate plate model.
