Optimized Analog Information Multiplexing Across Custom-Tailored MetaCavity Configurations
Philipp del Hougne, Matthieu Davy, Ulrich Kuhl
Combining tunable metasurfaces with chaotic cavities opens new avenues for finely tailored dynamic control of microwaves with programmable coding metacavities (PCMs). There is curr…
Microwave limiters implemented by coupled dielectric resonators based on a topological defect mode and CT-symmetry breaking
Mattis Reisner, Fabrice Mortessagne, Eleana Makri +2
We present a microwave realization of a reflective topological limiter based on an explicit self-induced violation of a charge-conjugation (CT) symmetry. The starting point is a bi…
Self-Shielded Topological Receiver Protectors
Mattis Reisner, Do Hyeok Jeon, Carsten Schindler +4
Receiver protectors (RPs) shield sensitive electronics from high-power incoming signals that might damage them. Typical RP schemes range from simple fusing and PIN diodes, to super…
A microwave realization of the chiral orthogonal, unitary, and symplectic ensembles
A. Rehemanjiang, M. Richter, U. Kuhl +1
Random matrix theory has proven very successful in the understanding of the spectra of chaotic systems. Depending on symmetry with respect to time reversal and the presence or abse…
Optimal Wave Fields for Micro-manipulation in Complex Scattering Environments
Michael Horodynski, Matthias Kühmayer, Andre Brandstötter +4
The manipulation of small objects with light has become an indispensable tool in many areas of research ranging from physics to biology and medicine. Here we demonstrate how to imp…
Localisation and transport in bidimensional random models with separable Hamiltonians
Gabino Corona-Patricio, Ulrich Kuhl, Fabrice Mortessagne +2
We consider two bidimensional random models characterised by the following features: a) their Hamiltonians are separable in polar coordinates and b) the random part of the potentia…
