Workshop "Waves in complex media"

The GDR MésoImage organized a workshop "Waves in complex media" in Grenoble from 11 to 13 December 2013.

Waves are all around us and we know that in many situations, "all waves behave in a similar way" (citation from L. Brillouin). This includes such phenomena as interference, diffraction, or scattering that can be observed with light, sound, seismic and matter waves. The universality of wave phenomena can be even stronger in complex environments where new phenomena emerge due to scattering from disorder, underlying symmetries of the system, or nonlinearity or the medium response. But it can also be lost because of peculiarities of a particular wave equation that turns out to be crucial in a specific complex environment. Our research group (groupement de recherche, GDR) MesoImage is aimed at the study of universal and nonuniversal aspects of wave propagation in complex environments with focus on applications for imaging and, more generally, noninvasive probing of complex media. In this spirit, the announced workshop will continue the tradition of interdisciplinary meeting that GDR organizes with participation of physicists (theoreticians and experimentalists), mathematicians, and geophysicists.

The workshop started on Wednesday, December 11, 2013 in the morning (the first talk will be scheduled at 10:30) and ended on Friday, December 13, 2013 (around 16:30). The program included talks covering the ensemble of GDR topics. A poster session and a social dinner were organized on Thursday, December 12.

The deadline for registration was November 11, 2013.

Registered participants were asked to take care of their transportation and lodging themselves except if they received different instructions from the Organizers. Here are lists of hotels near the railway station (convenient to get to the CNRS campus by bus) and in the city center. Note that the city center is 15 min walk from the railway station and another 25 min from the workshop place (CNRS campus). Bus 34 brings you to the CNRS campus from both the city center and the railway station (direction "Polygone scientifique - Chateau de Sassenage", step off at the station "Place de la Resistance").
