Wave propagation and control in complex media — From order to disorder 2021
- Poster
Scope
Understanding wave propagation in homogeneous media is the basis of classical imaging, sensing, or telecommunications techniques. The presence of disorder complicates these problems and the study of propagation in disordered media, associated with spatio-temporal wave control techniques, has enabled major advances in many fields, from acoustics to optics, including seismology and microwave. All these techniques share the same base, namely the wave propagation medium itself. This remains a subject of study in its own right, which we wish to address during this summer school, while keeping in mind the spirit of making crossings between the different communities of wave physics. Indeed, there is a multitude of different propagation media, each coming with its own specificities and its own terminology.
In particular, the usual propagation media are generally neither totally ordered nor totally disordered. The introduction of disorder correlations or particular symmetries introduces non-trivial behaviors for waves that open the way to new applications. Based on this observation, the main theme of our school is the study of the order/disorder transition in complex media. The objective is to share fundamentally multidisciplinary knowledge acquired by experts from different fields of research who face similar problems. The subjects treated will allow approaching the theoretical aspects related to complex environments (correlated disorder, topology, multiple scattering, disordered waveguides) as well as their practical applications (optical and microwave telecommunications, imaging, non-destructive testing, computation by physical systems, metamaterials).
A poster session will be organized to share recent results of the attendees.
