Quantification of the adhesion of metal thin film interfaces by picosecond acoustics

Alejandro Vital Juarez, Arnaud Devos, Jean-Michel Desmarres

Thin films are widespread in numerous fields: engineering, electronics, optics, biomedical, space and many more. They are largely used and require a flawless quality. One of the most important parameters is the adhesion of a layer with the substrate. Different methods of measuring the adhesion are…

Development of Surface Acoustic Wave pressure sensors for monitoring concrete structures

Hassan Alhousseini, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Rivart, Marc Poorteman, Maurice Gonon, Gregory Matric, Mohamed Rguiti, Christine Peligris

For many years surface acoustic waves (SAW) have been used in manufacturing electronic components for industrial and sensing applications. Due to the absence of an embedded electronic system and the possibility of wireless communication this technology can offer a great solution for sensing in…

High-frequency limits of graphene field-effect transistors with velocity saturation

Quentin Wilmart, Mohamed Boukhicha, Holger Graef, David Mele, José Palomo, Michael Rosticher, Takashi Taniguchi, Kenji Watanabe, Vincent Bouchiat, Emmanuel Baudin, Jean-Marc Berroir, Erwann Bocquillon, Gwendal Fève, Emiliano Pallecchi, Bernard Plaçais

The current understanding of physical principles governing electronic transport in graphene field effect transistors (GFETs) has reached a level where we can model quite accurately device operation and predict intrinsic frequency limits of performance. In this work, we use this knowledge to analyze…

Hybridization of Love surface acoustic waves in SiO2/ST-Quartz structure with resonant pillars grafted on the meta-surface

Yuxin Liu, Abdelkrim Talbi, Cécile Ghouila-Houri, El Houssaine El Boudouti, Olivier Bou Matar, Philippe Pernod, Bahram Djafari-Rouhani

The control of propagating waves can be achieved by introducing defect states in the phononic structure of the electroacoustic devices. This work investigates the interaction of Love waves in cavity-containing holey SiO2/Quartz structure with grafted Ni pillars. An optimal sized cavity in the holey…

Augmenting sensitivity of surface plasmon resonance (SPR) sensors with the aid of anti-reflective coatings (ARCs)

Das Cm, Ouyang Ql, Kang Lx, Guo Y, Dinh Xq, P. Coquet, Yong Kt

Surface plasmon resonance (SPR)-based biosensors are an integral and indispensable aspect of present-day pathology, owing to its efficient real-time and label-free detection capabilities. Enhancing the sensitivity of these sensors is of paramount importance as it indirectly affects the detection…

Serial interference cancellation for improving uplink in LoRa-like networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Guillaume Ferré, Laurent Clavier

In this paper, we present a new receiver design, which significantly improves performance in the Internet of Things networks such as LoRa, i.e., having a chirp spread spectrum modulation. The proposed receiver is able to demodulate multiple users simultaneously transmitted over the same frequency…

Anomaly Detection in Surveillance Videos by Future Appearance-motion Prediction

Tuan-Hung Vu, Sebastien Ambellouis, Jacques Boonaert, Abdelmalik Taleb-Ahmed

Anomaly detection in surveillance videos is the identification of rare events which produce different features from normal events. In this paper, we present a survey about the progress of anomaly detection techniques and introduce our proposed framework to tackle this very challenging objective.…

Estimation of the number of persons in a reverberant environment using bistatic radar

Marwan Yusuf, Brecht de Beelde, Emmeric Tanghe, Eli de Poorter, Luc Martens, Pierre Laly, Davy Gaillot, M. Lienard, Wout Joseph

The theory of room electromagnetics provides a simple characterization of indoor microwave propagation. By considering the indoor environment as a lossy cavity, the exponential decay rate of the power-delay profile is related to the total absorption inside the room. In this paper, we explore the…
