Ultra-hydrophobic biomimetic transparent bilayer thin film deposited by atmospheric pressure plasma

Manon Saget, Nicolas Nuns, Philippe Supiot, Corinne Foissac, Séverine Bellayer, Kevin Dourgaparsad, Pierre-Alexandre Royoux, Guillaume Delaplace, Vincent Thomy, Yannick Coffinier, Maude Jimenez

An open-air atmospheric pressure plasma was used to deposit ultrahydrophobic bilayer coatings. The plasma setup was tuned, allowing the successive injection in the post-discharge of two monomers. To the best of our knowledge, no study describes the successive deposition by atmospheric plasma of two...

Photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

Charbel Tannoury, Victor Merupo, Giuseppe Di Gioia, Vanessa Avramovic, David Troadec, Jean-François Lampin, Guillaume Ducournau, Steffen Breuer, Björn Globisch, Stefano Barbieri, Robert B Kohlhaas, Emilien Peytavit

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber...

CW Laser Emission up to 5 THz Using Optically Pumped Water Molecules

L. Juppet, Alexandra Khabbaz, Gaël Mouret, Jean-Francois Lampin, Olivier Pirali

In this work we discuss the use of a new molecule (deuterated water, D 2 O) to produce THz radiation using a midinfrared quantum cascade laser (MIR-QCL) pumped molecular laser. The molecular gain factor was used to determine the most favorable laser lines and several laser lines were measured up to...

High precision molecular laser frequency measurements using a THz frequency comb

Alexandra Khabbaz, L. Juppet, O. Pirali, Jean-Francois Lampin, Francis Hindle, Gaël Mouret

Molecular lasers are powerful sources of continuous-wave THz radiation that can be used as local oscillators for heterodyne receivers. In this work we show that it is possible to measure precisely their emission frequency using a simple setup based on a THz frequency comb referenced to a microwave...

Evaluation of Power-of-two Quantization for Multiplier-less Near-Memory and In-Memory Computing Schemes for Biomedical Applications

Antoine Gautier, Benoit Larras, Olev Märtens, Deepu John, Antoine Frappé

Embedded Artificial Intelligence and Artificial Neural Networks and their implementation at the edge, as close as possible to the sensors, is an opportunity to develop biomedical applications such as long-term monitoring or point-of-care devices, but the implementation of such networks is...

Développement d’une interface utilisateur interactive pour l’enseignement du traitement de signal

Nikolay Smagin, Lynda Chehami

Dans l'apprentissage de traitement du signal, les connaissances formelles (théorèmes et lois) se fait généralement en lien avec la pédagogie dans le souci de mieux les faire appréhender et assimiler par les étudiants. Ces concepts fondamentaux sont parfois difficiles à enseigner dans le schéma...

Flight-Testing of a MEMS Wall Shear Stress Thermal Sensor on a Microlight Aircraft

C. Ghouila-Houri, T. Arnoult, A. Mazzamurro, S. Kern, R. Viard, D. Teillet, E. Palfi, E. Garnier, Abdelkrim Talbi, P. Pernod

This paper reports the realization of thermal MEMS (Micro Electro-Mechanical Systems) sensors designed for wall shear stress measurement during real flight on a microlight aircraft. Based on constant temperature anemometry and calorimetric principle, the micro-sensors measure the viscous shear...

Détection et imagerie des BVID dans des matériaux composites

Pierre Goislot, Guillemette Ribay, Emmanuel Moulin, Lynda Chehami

Les BVID pour Barely Visible Impact Damage dans les matériaux composites sont un problème grandissant au sein de l’industrie aéronautique. Ces derniers peuvent apparaître lors des phases de maintenance ou durant le vol et sont quasiment impossibles à détecter à l’oeil nu. Bien que de très petite...
