Pillar-type acoustic metasurface

Yabin Jin, Bernard Bonello, Rayisa P. Moiseyenko, Yan Pennec, Olga Boyko, Bahram Djafari-Rouhani

We theoretically investigate acoustic metasurfaces consisting of either a single pillar or a line of identical pillars on a thin plate, and we report on the dependence on the geometrical parameters of both the monopolar compressional and dipolar bending modes. We show that for specific dimensions…

Microstructuration of Silicon Surfaces Using Nanoporous Gold Electrodes

E Torralba, Mathieu Halbwax, T El Assimi, V. Magnin, Joseph Harari, Jean-Pierre Vilcot, Sylvain Le Gall, Raphaël Lachaume, C Cachet-Vivier, Stéphane Bastide

Etching is a key process in the fabrication of silicon (Si) microstructures that are essential for several component families used in microelectronics, photonics and photovoltaics, among others. A large variety of microstructuring technologies exists nowadays (e.g. wet/dry etchings based on photo/…

IEEE 802.11n Communications in the Presence of Frequency-Sweeping Interference Signals

Virginie Deniau, Christophe Gransart, Grecia Romero, Eric Pierre Simon, Joumana Farah

This paper presents an analysis of the impact of intentional electromagnetic (EM) interferences on the performance of Wi-Fi communications. The goal is to analyze the susceptibility of orthogonal frequency-division multiplexing (OFDM) signals and to understand how certain parameters of the…, Cet article présente une analyse de l'impact des interférences électromagnétiques intentionnelles (IEMI) sur la performance des communications Wi-Fi. L'objectif est d'analyser la susceptibilité des signaux de OFDM (Orthogonal Frequency Division Multiplex ) et de comprendre comment…

Energy Consumption Models For MISO-UWB and TR-MISO-UWB Systems

Adil El Abboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

this paper, an energy consumption model is developed and exploited to evaluate the electrical energy consumption of ultra-wideband impulse radio (UWB-IR) systems. We develop the energy consumption models and our comparative study, on the one hand, for a system based single-input singleoutput (SISO…

The influence of the presence of a defect in a structure on the cross-correlation, application to the tubular structure

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

The aim of this paper is to verify experimentally the constant possibility of performing a Structural Health Monitoring (SHM) in a medium by studying the ambient noise present therein. First, we will illustrate the equivalence between the Green's function and the cross-correlation, then we…

A text-dependent speaker-recognition system

Dany Ishac, Antoine Abche, Elie Karam, Georges Nassar, Dorothée Debavelaere-Callens

In this work, a voice recognition approach is developed and presented. It is a based on acquiring the signal of vocal cords' vibrations of a person using a piezoelectric transducer element attached on a collar wrapped around the neck. The recognition is then based on the vocal cords vibrations…

Passive UHF RFID system evaluation in a retail environment

Hadi Farhat, Plamen Iliev, Philippe Mariage, Nathalie Rolland

The work in this paper presents the study of the influence of a particular environment on the performances of passive UHF RFID tags attached to products presented in a retail store. The effects of the near-field environment and of the far field environment are successively and separately…

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling…

Iron minerals within specific microfossil morphospecies of the 1.88 Ga Gunflint Formation

Kevin Lepot, Ahmed Addad, Andrew H. Knoll, Jian Wang, David Troadec, Armand Béché, Emmanuelle J. Javaux

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities…
