Dispersion of IDT-induced high-frequency surface acoustic waves - Application to the mechanical and dimensional characterization of mesoporous silicon

Tahar Kadi, Marc Duquennoy, Katir Ziouche, Mohammadi Ouaftouh, Nikolay Smagin

A method based on the dispersion of surface acoustic waves (SAW) is proposed for the effective characterization of mesoporous silicon (MPS) layers with the possibility of estimating Young's modulus and the thickness of the porous layer, as well as the porosity. For this purpose, IDT were…

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…

Massive radio channel sounder architecture for 5G mobility scenarios: MaMIMOSA

Pierre Laly, Davy Gaillot, Gauthier Delbarre, M. van den Bossche, G. Vermeeren, F. Challita, E. Tanghe, Eric Pierre Simon, W. Joseph, L. Martens, M. Lienard

This paper presents a real-time 64 x 16 massive MIMO channel sounder based on space-frequency division multiplexing and antenna subarray switching, giving a large possibility of antenna allocation and frequency tone between 2 and 12 GHz. This channel sounder called Massive MIMOSA or MaMIMOSA…

Scaling law, confined and surface modes in photonic fibonacci stub structures: theory and experiment

Hassan Aynaou, Abdelkader Mouadili, Noama Ouchani, El Houssaine El Boudouti, Abdellatif Akjouj, Bahram Djafari-Rouhani

We investigate both theoretically and experimentally the properties of electromagnetic waves propagation and localization in periodic and quasi-periodic stub structures of Fibonacci type. Each block constituting the Fibonacci sequence (FS) is composed of an horizontal segment and a vertical stub.…
