New developments towards seismic metamaterials
The META-FORET project is a large-scale wave manipulation with a multidisciplinary approach devised by a team composed of physicists, geophysicists and engineers.
The goal of the META-FORET project is to demonstrate that metamaterial physics that are classically observed at small scale in optics or acoustics as a way to cancel or bend waves can exist at the very large scale in geophysics.

In practice, the goal of the META-FORET project is to achieve two ambitious and novel experiments (...)

Surface wave interacting with resonating trees
The propagation of seismic waves in a 2D halfspace is a well-known problem in numerical seismology and modeled by solving the P- SV elastic wave equation (P: Primary or compressional wave, SV: vertically polarized shear or Secondary wave), but its coupling with resonating tree-like elements is rather unusual. The accuracy of the method has been thoroughly tested using plate and rods as input model and it has delivered excellent results. The (...)
DATA available for Academic Research
Each data set proposed below may be quite large. Be aware that the download could last a certain amount of time. The data come in Matlab format with one or a few codes to read / plot the data. There is also a Readme file and some pictures that explains very shortly the acquisition set-up and, sometimes, one scientific paper that was published from this data set.
The idea is to promote collaborative research. Of course, you can download the data and (...)
