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…

Electronic-components less fully textile multiple resonant combiners for body-centric near field communication

Baptiste Garnier, Philippe Mariage, François Rault, Cédric Cochrane, Vladan Koncar

Smart and e-textiles have nowadays an important increasing place in the garment industry. The rise of embedded telecommunications, especially smartphones in our pocket, enables us to provide a power source and a wireless link for smart textiles. The main issue is to develop garments able to receive…

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…

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…
