Measuring Dirac Cones in a Sub-Wavelength Metamaterial
Simon Yves, Thomas Berthelot, Mathias Fink +2
The exciting discovery of bi-dimensional systems in condensed matter physics has triggered the search of their photonic analogues. In this letter, we describe a general scheme to r…
Turning Optical Complex Media into Universal Reconfigurable Linear Operators by Wavefront Shaping
Maxime W. Matthès, Philipp del Hougne, Julien de Rosny +2
Performing linear operations using optical devices is a crucial building block in many fields ranging from telecommunication to optical analogue computation and machine learning. F…
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…
Locally Polarized Wave Propagation through Metamaterials' Crystallinity
Simon Yves, Thomas Berthelot, Geoffroy Lerosey +1
Wave propagation control is of fundamental interest in many areas of Physics. It can be achieved with wavelength-scaled photonic crystals, hence avoiding low frequency applications…
Leveraging Chaos for Wave-Based Analog Computation: Demonstration with Indoor Wireless Communication Signals
Philipp del Hougne, Geoffroy Lerosey
In sight of fundamental thermal limits on further substantial performance improvements of modern digital computational processing units, wave-based analog computation is becoming a…
