Enhancing LSPR sensitivity of Au gratings through graphene coupling to Au film

Thomas Maurer, Rana Nicolas, Gaëtan Lévêque, P. Subramanian, Julien Proust, Jérémie Béal, Silvere Schuermans, Jean-Pierre Vilcot, Z. Herro, M. Kazan, Jerome Plain, Rabah Boukherroub, Abdellatif Akjouj, Bahram Djafari-Rouhani, Pierre-Michel Adam, Sabine Szunerits

A particular interesting plasmonic system is that of metallic nanostructures interacting with metal films. As the localized surface plasmon resonance (LSPR) behavior of gold nanostructures (Au NPs) on the top of a gold thin film is exquisitely sensitive to the spacer distance of the film-Au NPs, we…

F center in lithium fluoride revisited : comparison of solid-state physics and quantum-chemistry approaches

Ferenc Karsai, Paul Tiwald, Robert Laskowski, Fabien Tran, David Koller, Stefanie Gräfe, Joachim Burgdörfer, Ludger Wirtz, Peter Blaha

We revisit the theoretical description of the F color center in lithium fluoride employing advanced complementary ab initio techniques. We compare the results from periodic supercell calculations involving density-functional theory (DFT) and post-DFT techniques with those from the embedded-cluster…

Effect of passivation on microwave power performances of AlGaN/GaN/Si HEMTs

H. Mosbahi, M. Charfeddine, M. Gassoumi, H. Mejri, Christophe Gaquière, Bertrand Grimbert, M.A. Zaidi, H. Maaref

This paper reports on the use of plasma assisted molecular beam epitaxy of AlGaN/GaN high electron mobility transistors (HEMTs) grown on silicon substrate. Surface passivation effects on AlGaN/GaN HEMTs were studied using SiO2/SiN dielectric layers grown by plasma enhanced chemical vapor deposition…

Mechanical damage assessment of polymer-matrix composites using active infrared thermography

Walid Harizi, S. Chaki, Gérard Bourse, Mohamed Ourak

The present work uses an active form of the infrared (IR) thermography technique for monitoring and characterization of the damage of glass fibers reinforced Polymer-Matrix Composites (PMCs) following an experimental protocol based on a monotonic tensile test with constant stress steps. The active…

Simultaneous bandgaps in LiNbO3 phoxonic crystal slab

Quentin Rolland, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik, Yan Pennec, Bahram Djafari-Rouhani, Vincent Laude

We study simultaneous photonic and phononic crystal slabs created in Z-cut lithium niobate membranes. Bandgaps for guided waves are identified using the three-dimensional finite element method (FEM). Three lattices are considered: the square, the hexagonal, and the honeycomb lattices. We…

CW Radar for Monitoring Water-to-Cellular Concrete

Kamel Haddadi, Tuami Lasri

The physical deterioration of concrete structures is mainly caused by their moisture content. Consequently, methods dedicated to contactless, non-destructive and real-time monitoring of moisture content levels are required to control the deterioration of buildings. In this study, we propose an…

Active control of a piezoelectric phononic crystal using electrical impedance

Sid Ali Mansoura, Pierre Maréchal, Bruno Morvan, Anne-Christine Hladky, Bertrand Dubus

We consider a one dimensional Phononic Crystal (PC) based on a stack of plates including piezoelectric layers. The model takes into account electrical external circuit connected to the piezoelectric layers with the exception of the layer for which the impedance is evaluated. Only longitudinal waves…

Network games under strategic complementarities

Mohamed Moez Belhaj, Yann Bramoullé, Frédéric Deroïan

We study network games under strategic complementarities. Agents are embedded in a fixed network. They choose a positive, continuous action and interact with their network neighbors. Interactions are positive and actions are bounded from above. We first derive new sufficient conditions for…

Model calculation of the magnetic induction generated by magnetic nanoparticles flowing into a microfluidic system. Performance analysis of the detection

Kamel Fodil, Matthieu Denoual, Christophe Dolabdjian, A. Treizebre, Vincent Senez

This paper presents a mathematical model of the detection of the magnetic nanoparticles (MNPs) flowing into a microchannel. To validate the model, the experimental measurements were performed using a ferrofluid and a giant magneto impedance microwire made up of CoFeSiBNb alloy as a sensor. The good…
