Experimental demonstration of a mmWave passive access point extender based on a binary reconfigurable intelligent surface
Vladislav Popov, Mikhail Odit, Jean-Baptiste Gros +5
As data rates demands are exploding, 5G will soon rely on mmWaves that offer much higher bandwidths. Yet at these frequencies, attenuation and diffraction of waves require point to…
A Reconfigurable Intelligent Surface at mmWave based on a binary phase tunable metasurface
Jean-Baptiste Gros, Vladislav Popov, Mikhail A. Odit +2
Originally introduced in the early 2010's, the idea of smart environments through reconfigurable intelligent surfaces (RIS) controlling the reflections of the electromagnetic waves…
Structure-Composition Correspondence in Crystalline Metamaterials for Acoustic Valley-Hall Effect and Unidirectional Sound Guiding
Simon Yves, Geoffroy Lerosey. Fabrice Lemoult
Recently, the domain of topological insulators in condensed matter physics has been teeming with intriguing and very exciting discoveries. Notably, the capacity of guiding currents…
Uncorrelated Configurations and Field Uniformity in Reverberation Chambers Stirred by Tunable Metasurfaces
Jean-Baptiste Gros, Geoffroy Lerosey, Fabrice Mortessagne +2
Reverberation chambers are currently used to test electromagnetic compatibility as well as to characterize antenna efficiency, wireless devices, and MIMO systems. The related measu…
Wave Chaos in a Cavity of Regular Geometry with Tunable Boundaries
Jean-Baptiste Gros, Philipp del Hougne, Geoffroy Lerosey
Wave chaotic systems underpin a wide range of research activities, from fundamental studies of quantum chaos via electromagnetic compatibility up to more recently emerging applicat…
Optimal Communication Channels in a Disordered World with Tamed Randomness
Philipp del Hougne, Mathias Fink, Geoffroy Lerosey
Multi-channel wireless systems have become a standard solution to address our information society's ever-increasing demand for more information transfer. The ultimate bound on the…
Left-handed Band in an Electromagnetic Metamaterial Inducedby Sub-wavelength Multiple Scattering
Simon Yves, Thomas Berthelot, Mathias Fink +2
Due to the deep sub-wavelength unit cell in metamaterials, the quasi-static approximation is usually employed to describe the propagation. By making pairs of resonators, we highlig…
Shaping Microwave Fields using Non-Linear Unsolicited Feedback: Application to Enhanced Energy Harvesting
Philipp del Hougne, Mathias Fink, Geoffroy Lerosey
Wavefront Shaping has emerged over the past decade as a powerful tool to control wave propagation through complex media, initially in optics and more recently also in the microwave…
