Periodic Reporting for period 2 - WAVES (Waves and Wave-Based Imaging in Virtual and Experimental Environments)
Okres sprawozdawczy: 2017-01-01 do 2018-12-31
All the planned workshops, and several short courses have taken place as explained in detail in our report; besides strengthening their scientific background and helping them in pursuing their research projects, these activities successfully fostered the interaction of ESRs, who are now themselves connected in a network that will last in the coming years. As explained in our report and deliverable descriptions, WAVES research has contributed new theoretical formulations (e.g. on Marchenko imaging; the role of scattering in ambient-noise interferometry, etc.); new experimental data (experiments on bone conduction; on elastography in several different materials; on acoustic cloaking; metamaterials, etc.); and new interdisciplinary applications (new links between seismology and the medical sciences; seismology and physical acoustics; seismology and atmospheric infrasound acoustics, etc.).
Research advances associated with WAVES will partly be presented to the general public through an exhibition planned at FocusTerra in Zurich, Switzerland.
All thesis projects in WAVES are at the cutting edge of current science, and go beyond the state of the art as explained in our original proposal and final report. Detailed and updated research plans for all our ESRs can be read online through the WAVES website: http://www.waves-itn.eu/en/research.html. In particular, some of the most sophisticated physical acoustics laboratories worldwide participated in WAVES, including LMA at Marseille (CNRS), ISTerre Grenoble (CNRS), Institut Langevin (ESPCI) and the geotechnology lab at TU Delft. Two new laboratories, RFPC at UEDIN and WaveLab at ETH, are growing and have been harnessed in the framework of WAVES. WaveLab provides the only experimental setup worldwide where perfect acoustic time reversal can in principle be achieved, via a dense array of transducers covering all the walls of a closed tank. The RFPC lab is a unique facility, allowing (through the work of WAVES ESRs) to predict real-future fracturing of materials under stress: this research is naturally relevant to the topic of earthquake forecast.
WAVES also forged new, unique interdisciplinary links: see for example the three research projects involving INSERM, UPMC and CNRS (Lyon, Paris, Grenoble), which are based on the collaboration between bio-medical researchers, seismologists, acousticians.
