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...

Thermoelectric Properties of Benzothieno-Benzothiophene Self-Assembled Monolayers in Molecular Junctions

Sergio Gonzalez-Casal, Rémy Jouclas, Imane Arbouch, Yves Geerts, Colin van Dyck, Jérôme Cornil, Dominique Vuillaume

We report a combined experimental (C-AFM and SThM) and theoretical (DFT) study of the thermoelectric properties of molecular junctions made of self-assembled monolayers on Au of thiolated benzothieno-benzothiophene (BTBT) and alkylated BTBT derivatives (C8-BTBT-C8). We measure the thermal...

Retention or repulsion forces induced by bubbles trapped at the base of an immersed microparticle on a substrate

Anna Ipatova, Alexis Duchesne, H N Yoshikawa, Pascal Mariot, Corenthin Leroy, Christine Faille, Ichiro Ueno, Georg F Dietze, Farzam Zoueshtiagh

We explore the potential for air bubble entrapment beneath micrometer-sized particles following immersion. This investigation employs theoretical, numerical, and experimental methodologies, with a focus on the wetting characteristics of both the particle and its substrate. These properties are...

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,...

Reverse-Bias Current Hysteresis at Low Temperature in GaN Schottky Barrier Diodes

In this paper, we report an analysis of reverse current mechanisms observed in GaN Schottky barrier diodes leading to hysteretic behavior of the I\textendashV curves at low temperature. By means of DC measurements from 33 to 475\,K, we demonstrate the presence of two leakage mechanisms when...

Switchable SAW Resonators and Ladder Filters Composed of Interdigitated Combs

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, A.-C. Hladky-Hennion

This work presents the development of switchable SAW resonators fabricated on a LiNbO3 substrate, which use the Electrical Bragg Bandgap concept to control the resonance frequency. The modification of the electrical condition of electrode arrays shifts their bandgap center frequency which in turn...
