Fabry-Pérot and Friedrich-Wintgen bound states in the continuum in a photonic triple-stub cavity

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are zero-width (infinite lifetime) trapped eigenmodes that remain conf ined in the system even though they coexist with a continuum of extended states. The resulting high-frequency resonances may have significant applications in photonic integrated circuits,…

Fault detection and localization in unshielded twisted pair cable based on observability analysis and reflectometry experimental measurements.

Hermine Judith Idellette Som, Vincent Cocquempot, Virginie Degardin

In this paper, an efficient method is proposed for detecting and locating a soft fault, i.e. a physical degradation, in a Y -shaped network of unshielded twisted pair cables. The method uses jointly the observability analysis and time-frequency domain reflectometry experimental measurements. The…

Exploring the properties of higher-order Tamm plasmons for liquid and gas detection

O. Haidar, Baptiste Mathmann, Y. Dusch, Mohamed Boutghatin, E. Boudouti, G. Lévêque, A. Mir, A. Akjouj, A. Talbi

In this study, we present a numerical analysis of the higher-order Tamm plasmons for the design of a gas and liquid sensor. These plasmons are induced by a structure consisting of a cavity placed between the SiO2/Si3N4 Bragg grating and a finite layer of gold. This configuration is excited without…

An Incremental Time-Domain Mixed-Signal Matrix-Vector-Multiplication Technique for Low-Power Edge-AI

Kévin Hérissé, Benoit Larras, Bruno Stefanelli, Andreas Kaiser, Antoine Frappé

This paper proposes a time-domain mixed-signal computing architecture for Matrix-Vector Multiplication suited for embedded in-memory computing applications. The system leverages the low data rate of sensors’ data in embedded AI applications to target an energy-efficient implementation of the matrix…

Enhancing Tamm Plasmon Sensor Performance using Nanostructured Gold Grating and Porous Materials

O. Haidar, Baptiste Mathmann, Yannick Dusch, Mohamed El Barghouti, Romain Viard, Gaëtan Lévêque, El Houssaine El Boudouti, Abdellah A. Mir, A. Talbi, Abdellatif Akjouj

In this paper, we introduce a gas sensor concept consisting of a nanostructured gold grating coupled with a Distributed Bragg Reflector. This coupling makes it possible to obtain plasmonic Tamm states where excitation is possible at normal incidence and does not require the use of Kretschmann…

Ultrafast skyrmion generation by plasmonic resonance

W. Al Saidi, Yannick Dusch, M. Myint, Nicolas Tiercelin, R. Sbiaa

This theoretical study unveils the potential for ultrafast skyrmion generation in magnetic thin films, driven by the remarkable plasmonic properties of gold nanoparticles. By combining the plasmonic, photothermal, and micromagnetic analysis, we explore size-dependent light absorption, resonance…

Efficiency and Accuracy Evaluation of Multiple Diffusion‐Weighted MRI Techniques Across Different Scanners

Frederik Crop, Clémence Robert, Romain Viard, Julien Dumont, Marine Kawalko, Pauline Makala, Xavier Liem, Imen El Aoud, Aicha Ben Miled, Victor Chaton, Lucas Patin, David Pasquier, Ophélie Guillaud, Benjamin Vandendorpe, Xavier Mirabel, Luc Ceugnart, Camille Decoene, Thomas Lacornerie

Background The choice between different diffusion-weighted imaging (DWI) techniques is difficult as each comes with tradeoffs for efficient clinical routine imaging and apparent diffusion coefficient (ADC) accuracy. Purpose: To quantify signal-to-noise-ratio (SNR) efficiency, ADC accuracy,…
