Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen…

Vertical Engineering for Large Brillouin Gain in Unreleased Silicon-Based Waveguides

L. Mercadé, A.V. Korovin, Yan Pennec, J. Ahopelto, Bahram Djafari-Rouhani, A. Martínez

Strong acousto-optic interaction in high-index waveguides and cavities generally requires the releasing of the high-index core to avoid mechanical leakage into the underlying low-index substrate. This complicates fabrication, limits thermalization, reduces the mechanical robustness, and hinders…

Topological surface wave metamaterials for robust vibration attenuation and energy harvesting

Xinyue Wu, Yabin Jin, Abdelkrim Khelif, Xiaoying Zhuang, Timon Rabczuk, Bahram Djafari-Rouhani

We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the quantum valley Hall effect, a non-trivial bandgap is formed by breaking the inversion symmetry of the unit cell. A topological…

On The Necessity of Multiphysics Simulation Experiments in MEMS Teaching

Jinying Zhang, Wei-Jiang Xu, Xianmei Wu

Microelectromechanical system (MEMS) is an interdisciplinary research and education field. The multiphysics simulation can make the abstract theory on MEMS design concrete and improve the learning efficiency. A MEMS course design is presented in this paper. The content consists of fundamental…

Recognition of COVID-19 from CT Scans Using Two-Stage Deep-Learning-Based Approach: CNR-IEMN

Fares Bougourzi, Riccardo Contino, Cosimo Distante, Abdelmalik Taleb-Ahmed

Since the appearance of the COVID-19 pandemic (at the end of 2019, Wuhan, China), the recognition of COVID-19 with medical imaging has become an active research topic for the machine learning and computer vision community. This paper is based on the results obtained from the 2021 COVID-19 SPGC…

Efficient combinations of NOMA with distributed antenna systems based on channel measurements for mitigating jamming attacks

Joumana Farah, Eric Pierre Simon, Pierre Laly, Gauthier Delbarre

This study aims at proposing new efficient combinations of distributed antenna systems (DAS) with non orthogonal multiple access (NOMA) for combating the influence of harmful jamming on a downlink transmission system. A large set of practical channel measurements was performed in an indoor work…
