Virtual VNA 2.0: Ambiguity-Free Scattering Matrix Estimation by Terminating Not-Directly-Accessible Ports with Tunable and Coupled Loads
Philipp del Hougne
We recently introduced the "Virtual VNA" concept which estimates the scattering matrix characterizing an arbitrarily complex linear reciprocal system with monomoda…
Agile Free-Form Signal Filtering with a Chaotic-Cavity-Backed Non-Local Programmable Metasurface
Fabian T. Faul, Laurent Cronier, Ali Alhulaymi +2
Filter synthesis is an inverse problem that is traditionally approached rationally by considering spatially disjoint resonators, approximating them as lumped elements, and engineer…
Training of Physical Neural Networks
Ali Momeni, Babak Rahmani, Benjamin Scellier +25
Physical neural networks (PNNs) are a class of neural-like networks that leverage the properties of physical systems to perform computation. While PNNs are so far a niche research…
Deeply Sub-Wavelength Localization with Reverberation-Coded-Aperture
Michael del Hougne, Sylvain Gigan, Philipp del Hougne
Accessing sub-wavelength information about a scene from the far-field without invasive near-field manipulations is a fundamental challenge in wave engineering. Yet it is well under…
Implementing Non-Universal Features with a Random Matrix Theory Approach: Application to Space-to-Configuration Multiplexing
Philipp del Hougne, Dmitry V. Savin, Olivier Legrand +1
We consider the efficiency of multiplexing spatially encoded information across random configurations of a metasurface-programmable chaotic cavity in the microwave domain. The dist…
