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.…

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…

Scanning Acoustic Microscopy versus Colored Picosecond Acoustics to detect interface defects in hybrid wafer bonding

Solene Bossut, Arnaud Devos, S Lhostis, E Deloffre, C Euvrard, F Dettoni, C Chaton

Nowadays, microelectronics is making progress in miniaturization and diversification of chips by 3D integration: dies are stacked together to gain space and performances. The stacking used here is called hybrid bonding [1], as stacked surfaces are heterogeneous: part Cu and part oxide. After the…

Utilisation du silicium nanostructuré dans un générateur thermoélectrique pour la réduction des pertes thermiques

Katir Ziouche, Ibrahim Bel-Hadj, Zahia Bougrioua

Dans cet article, nous présentons des microgénérateurs thermoélectriques (μTEG) planaires réalisés en technologie Silicium compatible CMOS, et destinés à la récupération de toute forme d’énergie thermique. Ceux-ci utilisent des matériaux faible coût, abondants et respectueux de l’environnement. La…, In this paper, we present a planar thermoelectric microgenerator (μTEG) based on CMOS-compatible silicon technology to harvest all forms of thermal energy. These have made by using low cost, abundant and eco-friendly materials. The heat harvesting has performed with a silicon concentrator. The…

Effects of the electrical limit conditions on the electromechanical behavior of piezoelectric transducer arrays

Abdelmajid Bybi, Adil Ammar, Mohammed Garoum, Sébastien Grondel, Ahmed Mzerd, Anne-Christine Hladky

Crosstalk is an undesirable phenomenon having a negative impact on the electroacoustic performance of ultrasonic transducer arrays, utilized in medical imaging and NDT applications. Indeed, when one element of a transducer array is excited, it generates parasitic voltages and/or displacement fields…

New Bacteriocins from Lacticaseibacillus paracasei CNCM I-5369 Adsorbed on Alginate Nanoparticles Are Very Active against Escherichia coli

Yanath Belguesmia, Noura Hazime, Isabelle Kempf, Rabah Boukherroub, Djamel Drider

Lacticaseibacillus paracasei CNCM I-5369, formerly Lactobacillus paracasei CNCM I-5369, produces bacteriocins that are remarkably active against Gram-negative bacteria, among which is the Escherichia coli-carrying mcr-1 gene that is involved in resistance to colistin. These bacteriocins present in…

Short-term reliability of high performance Q-band AlN/GaN HEMTs

R. Kabouche, K. Harrouche, Etienne Okada, F Medjdoub

We report on an on-wafer short-term 40 GHz RF reliability stress test comparison between a 3 nm versus 4 nm barrier thickness AlN/GaN HEMT technology showing state-ofthe-art power performances in the millimeter wave range. It is found that the barrier thickness in this highly strain heterostructure…
