The Centre National de la Recherche Scientifique (National Center for Scientific Research) is a public research organization under the responsibility of the French Ministry of Education and Research.
The Langevin Institute “Waves and Images” was created January 1st 2009. It is founded on the skills of the “Laboratoire Ondes et Acoustique” and of the “Laboratoire d’Optique Physique” of the school in order to develop at a world level the study of waves for new applications and new methods of imaging. The research conducted within this CNRS unit (UMR) goes from the basic and theoratical physics to the most elaborate applications, from multiwave imaging (acousto-optic, photo-acoustic, ultrasound or MR elastography) to the original focusing techniques (time reversal, inverse filter, controlled wavefront), through start-up foundation in biomedical, telecommunication, domotic, etc…
The project will be developed inside the team “Acoustic and Electromagnetic wave propagation in complex media”. This last years, this team performed many studies on the wave propagation of electromagnetic waves inside locally resonant materials.

- Key personnel
Dr. Julien de Rosny, Director of research at CNRS, is a Physicist specialist on wave propagation in ordered and disordered complex media. He has a large background both in acoustic and in electromagnetism. He published more than 60 papers in Peer Peview publications and book chapters. He holds about 10 patents on different domains: signal processing, telecom, antenna, … He is the co-creator of Time Reversal Communication companies.
Prix Diderot Innovation 2007 with Arnaud Tourin, Mathias Fink and Geoffroy Lerosey
Role in the project: Fundamental study of hybridization. Phenomenological models. Numerical simulations and experimental developments of the magnetic tunable volumetric antenna.
Dr. Mathias Fink is a professor of physics at the Ecole Superieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI ParisTech), Paris, France. In 1990 he founded the Laboratory “Ondes et Acoustique” at ESPCI that became in 2009 the Langevin Institute. In 2002, he was elected at the French Academy of Engineering, in 2003 at the French Academy of Science and in 2008 at the College de France on the Chair of Technological Innovation. Mathias Fink’s area of research is concerned with the propagation of waves in complex media and the development of numerous instruments based on this basic research. His current research interests include time-reversal in physics, wave control in complex media, super-resolution, metamaterials, medical ultrasonic imaging, ultrasonic therapy, multiwave imaging, acoustic smart objects, underwater acoustics, geophysics and telecommunications.He has developed different techniques in medical imaging (ultrafast ultrasonic imaging, transient elastography, supersonic shear imaging), wave control and focusing in complex media with time-reversal mirrors. He holds more than 65 patents, and he has published more than 400 peer reviewed papers and book chapters. 4 start-up companies with close to 300 employees have been created from his research (Echosens, Sensitive Object, Supersonic Imagine and Time Reversal Communications).
Anton Nikulin is a PhD student in Institut Langevin, ESPCI, PSL, CNRS. The title of his thesis is "Tunable metamaterials-based RF coils for MRI". Anton has published 2 journal papers. He is an co-author of one patent.
Role in the project: Numerical and experimental study of volume RF coils inspired by metamaterials.
Abdelwaweb Ourir received his engineering degree from ENIT (Tunis Tunisia) in 2003. He received his Ph.D. Degree in Physics from Paris Sud University (Orsay France) in 2007. Since 2008, he is a CNRS research engineer at the Institut Langevin (ESPCI), Paris, France. He has developed original devices based on passive and active metamaterials for antennas.
His current research interests include metamaterial based antennas, electromagnetic subwavelength imaging and wave propagation in artificial materials.
