Optimization of Active Reconfigurable Surfaces for Spatiotemporal MU-MIMO Wave Routing in Disordered Media: Application to the Cocktail-Party Problem
Frederic J. N. Jorgensen, Florent Dorlot, Constant Bourdeloux +4
We design an active reconfigurable intelligent surface (RIS) for acoustic multi-user multiple-input multiple-output (MU-MIMO) communication by solving a large-scale convex optimiza…
Single-Antenna Non-Line-of-Sight Matrix Imaging via Reconfigurable Intelligent Surfaces
Antton Goïcoechea, François Sarrazin, Theodosios Karamanos +3
Modern imaging and sensing in complex environments, ranging from biomedical diagnostics to wireless communication, relies on accurately measuring and then controlling the wave prop…
Elastic wavepackets crossing a space-time interface
Alexandre Delory, Claire Prada, Maxime Lanoy +3
The interaction between waves and evolving media challenges traditional conservation laws. We experimentally investigate the behavior of elastic wave packets crossing a moving inte…
Towards optimal spatiotemporal wavefront shaping for the cocktail party problem with inverse design of an acoustic reconfigurable metasurface in disordered media
Raphael Pestourie, Constant Bourdeloux, Fabrice Lemoult +2
Multiple-user multiple-input multiple-output applications have recently gained a lot of attention. Here, we show an efficient optimization formulation for the design of all the tem…
Exploiting spacetime symmetry in dissipative nonlinear multimode amplifiers for output control
Chun-Wei Chen, Kabish Wisal, Mathias Fink +2
Time-reversal symmetry enables shaping input waves to control output waves in many linear and nonlinear systems; however energy dissipation violates such symmetry. We consider a sa…
Topology Optimization for Microwave Control With Reconfigurable Intelligent Metasurfaces In Complex Media
Theodosios D. Karamanos, Mathias Fink, Fabrice Lemoult
Reconfigurable intelligent metasurfaces have been proposed as an efficient solution for improving wireless telecommunication systems in multiple scattering or reverberating media.…
Optimizing multi-user indoor sound communications with acoustic reconfigurable metasurfaces
Hongkuan Zhang, Qiyuan Wang, Mathias Fink +1
Sound in indoor spaces forms a complex wavefield due to multiple scattering encountered by the sound. Indoor acoustic communication involving multiple sources and receivers thus in…
