Equireflectionality and customized unbalanced coherent perfect absorption in asymmetric waveguide networks
Malte Röntgen, Olivier Richoux, Georgios Theocharis +4
We explore the scattering of waves in designed asymmetric one-dimensional waveguide networks. We show that the reflection between two ports of an asymmetric network can be identica…
Exceptional points of PT-symmetric reflectionless states in complex scattering systems
Clément Ferise, Philipp del Hougne, Simon Félix +2
We investigate experimentally and analytically the coalescence of reflectionless (RL) states in symmetric complex wave-scattering systems. We observe RL-exceptional points (EPs), f…
On-demand coherent perfect absorption in complex scattering systems: time delay divergence and enhanced sensitivity to perturbations
Philipp del Hougne, K. Brahima Yeo, Philippe Besnier +1
Non-Hermitian photonic systems capable of perfectly absorbing incident radiation recently attracted much attention both because fundamentally they correspond to an exotic scatterin…
Spatio-temporal wavefront shaping in a microwave cavity
Philipp del Hougne, Fabrice Lemoult, Mathias Fink +1
Controlling waves in complex media has become a major topic of interest, notably through the concepts of time reversal and wavefront shaping. Recently, it was shown that spatial li…
Intensity-only measurement of partially uncontrollable transmission matrix: demonstration with wave-field shaping in a microwave cavity
Philipp del Hougne, Boshra Rajaei, Laurent Daudet +1
Transmission matrices (TMs) have become a powerful and widely used tool to describe and control wave propagation in complex media. In certain scenarios the TM is partially uncontro…
