Comparison of Brillouin Light Scattering and Density of States in a Supported Layer: Analytical and Experimental Study

Ossama El Abouti, John Cuffe, El Houssaine El Boudouti, Clivia Sotomayor Torres, Emigdio Chavez-Angel, Bahram Djafari-Rouhani, Francesc Alzina

We provide a detailed analytical calculation of the Brillouin light scattering (BLS) intensity of a layer on a substrate, taking into account both photoelastic and moving boundary (ripple effect) mechanisms, and give a comparison between BLS intensity and density of states (DOS) to determine the…

Stiffening of nanoporous gold: experiment, simulation and theory

Claudio Melis, Giorgio Pia, Elisa Sogne, Andrea Falqui, Stefano Giordano, Francesco Delogu, Luciano Colombo

By combining electron microscopy measurements, atomistic simulations and elastic homogenization theory, we theoretically investigate the Young’s modulus of nanoporous Au structures. Based on atomistic replicas generated starting from experimental tomographic evidence, atomistic simulations reveal…

CNTFET-Based Ternary Multiply-and-Accumulate Unit

Amr Mohammaden, Mohammed Fouda, Ihsen Alouani, Lobna Said, Ahmed Radwan

Multiply-Accumulate (MAC) is one of the most commonly used operations in modern computing systems due to its use in matrix multiplication, signal processing, and in new applications such as machine learning and deep neural networks. Ternary number system offers higher information processing within…

Synthesis and characterization of palladium nanoparticles immobilized on graphene oxide functionalized with triethylenetetramine or 2,6-diaminopyridine and application for the Suzuki cross-coupling reaction

Maryam Mirza-Aghayan, Marzieh Mohammadi, Rabah Boukherroub

Graphene oxide (GO) was functionalized with two organic ligands, triethylenetetramine (TETA) or 2,6-diaminopyridine (DAP), followed by palladium nanoparticles (Pd NPs) for the synthesis of Pd NPs/GO-TETA and Pd NPs/GO-DAP nanocomposites, respectively. The two heterogeneous nanocomposites were fully…

Millimeter-Wave Phased Arrays and Over-the-Air Characterization for 5G and Beyond

Mattia Maggi, Syrine Hidri, Loic Marnat, Mauro Ettorre, Gerardo Orozco, Marc Margalef-Rovira, Christophe Gaquière, Kamel Haddadi

Millimeter-wave (mm-wave) technology is a viable candidate to address the growing data traffic in 5G wireless communication and beyond. However, challenges related to free-space propagation loss, atmospheric absorption, scattering, and nonline-of-sight propagation must be addressed to benefit from…

Enhanced Antibacterial Activity of Dermaseptin through Its Immobilization on Alginate Nanoparticles-Effects of Menthol and Lactic Acid on Its Potentialization

Noura Hazime, Yanath Belguesmia, Alexandr Barras, Mohamed Amiche, Rabah Boukherroub, Djamel Drider

Dermaseptin B2 (DRS-B2) is an antimicrobial peptide secreted by Phyllomedusa bicolor, which is an Amazonian tree frog. Here, we show that the adsorption of DRS-B2 on alginate nanoparticles (Alg NPs) results in a formulation (Alg NPs + DRS-B2) with a remarkable antibacterial activity against…

Système de vision neuro-inspirée : Application à la vision artificielle

Dimitri Henniquau, Pierre Falez, Philippe Devienne, Christel Vanbesien, Alexis Vlandas, A. Cappy, Virginie Hoel

L’architecture des systèmes numériques traditionnels est loin d’être optimale puisqu’un microprocesseur est tout autant une plaque chauffante qu’un calculateur (Intel Cooking [1]). Il devient donc urgent de proposer des architectures de traitement de l’information radicalement différentes, « neuro-…

Photonics-Based Near-Field Measurement and Far-Field Characterization for 300-GHz Band Antenna Testing

Yusuke Tanaka, Guillaume Ducournau, Cybelle Belem-Goncalves, Frederic Gianesello, Cyril Luxey, Issei Watanabe, Akihiko Hirata, Norihiko Sekine, Akifumi Kasamatsu, Shintaro Hisatake

In this study, photonics-based near-field measurement and far-field characterization in a 300-GHz band are demonstrated using an electrooptic (EO) sensor with planar scanning. The field to be measured is up-converted to the optical domain (1550 nm) at the EO sensor and delivered to the measurement…

THz photonics-based transmitter using multicore fiber combined with UTC-PD array for high data transmission in 300 GHz band

Bewindin Alfred Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, Pascal Szriftgiser, Karen Baudelle, Monika Cieslikiewicz-Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

This work aims at illuminating an UTC-PD array with a multicore fiber towards multiple THz carrier generation. This photonics-based transmitter is expected to increase either the data rate via spatial multiplexing on different carriers or the emitted THz-power and therefore the transmission reach…
