Workshop Cargèse 2013


CONTROLLING THE PROPAGATION OF WAVES IN COMPLEX MEDIA : FROM SHAPING WAVE FIELDS TO DESIGNING SMART MATERIALS

May 27th - June 1st, 2013
Institut Scientifique de Cargèse, Corsica, France
Director  : Mathias Fink.
Organized by : Julien de Rosny, Geoffroy Lerosey, and Alexandre Aubry.

Controlling the propagation of acoustic, electromagnetic and even matter waves, is of fundamental interest for many applications ranging from imaging the living and detecting hazardous components, to information processing and stealth technology. In the past decades, there has been many proposals in this regards, which can be separated within two main categories. On the one hand, it has been shown that one can tame wavefields in order to take advantage of the complexity of propagation media to for instance focus waves or image various objects. This can be realized in the temporal domain using the concept of time reversal, which was originally demonstrated in acoustics and then in electromagnetism, or in the spatial domain using the wavefront shaping techniques developed in optics. On the other hand, one can force waves along desired paths through a careful design of manmade materials. This can be achieved using the concept of photonic and phononic crystals, which can guide and confine waves through Bragg interferences, or opting for metamaterials and related concepts such as conformal transformations, cloaking and negative refraction. Those concepts are closely intricate, and in the past few years there has been clear demands of convergence between the researchers of those various communities. Our school aims at gathering their main experts in a unique workshop which will be devoted to the control of waves, whatever their nature, in random and complex media. This will permit to the more experienced scientists to share and confront the concepts developed in their own field of research with others, and to the younger audience to acquire a solid and broad knowledge of wave control in complex media from the best experts worldwide.

The registration is closed since the workshop is full.
