[Invited] Optimization of quasi-periodically ribbed structures to improve stealth and discreteness of underwater vehicles

Bertrand Dubus, Charles Croënne, Samuel Deleplanque, Anne-Christine Hladky

Acoustic stealth and discreteness of underwater vehicles are important issues in underwater acoustics. These vehicles are constituted of shells which are periodically reinforced by ribs. Acoustic fields radiated or scattered by such structures are strongly affected by phenomena related to this…

Investigation of cross-coupling in piezoelectric transducer arrays and correction

Abdelmajid Bybi, Sébastien Grondel, Ahmed Mzerd, Christian Granger, Mohammed Garoum, Jamal Assaad

Cross-coupling in piezoelectric transducer arrays is an undesirable phenomenon which decreases the performance of these devices. Indeed, when one element of a transducer is driven, it generates parasitic displacement fields at the radiating surfaces of the neighboring elements, which changes the…

Low‐loss broadband (DC to 220 GHz) S‐CPW to S‐CPS transition for S‐CPS coplanar probing

Abdelhalim Saadi, Marc Margalef-Rovira, L. Vincent, Sylvie Lepilliet, Christophe Gaquière, Philippe Ferrari

The practical issue of probing coplanar stripline (CPS) structures is addressed in this Letter. A compact slow-wave coplanar waveguide (S-CPW) to slow-wave CPS (S-CPS) transition was designed and fabricated in a 55 nm BiCMOS process of STMicroelectronics. The signal strips of the slow-wave CPW and…

Performance Evaluation of Multi-Carrier Modulation Techniques in High Speed Railway Environment with Impulsive Noise

Michel Saideh, Yamen Alsaba, Iyad Dayoub, Marion Berbineau

Multi-Carrier Modulation (MCM) techniques are considered as one of the main building blocks for future railway communication systems. This is due to their ability to handle spectrum scarcity and asynchronous communications dilemmas. In this paper, we evaluate the performance of different…

Gigahertz frequency graphene transistor, high yield process and good stability under strain

Wei Wei, S. Mhedhbi, S. Salk, T. Levert, O. Txoperena, Emiliano Pallecchi, H. Happy

We report a bonding free fabrication process suitable for flexible substrate based graphene field effect transistors (GFETs). Transistors with different gate length (100 nm, 200 nm and 300 nm) and different channel width (12µm,24µm and 50µm) are successfully fabricated on Kapton substrate. The…

Massive MIMO channel characterization and propagation-based antenna selection strategies : application to 5G and industry 4.0, Caractérisation des canaux massive MIMO et stratégies de sélection d'antenne : application pour la 5G et l'industrie 4.0

Frédéric Challita

Continuous efforts have been made to boost wireless systems performance, however, current wireless networks are not yet able to fulfill the many gaps from 4G and requirements for 5G. Thus, significant technological breakthroughs are still required to strengthen wireless networks. For instance, in…, Dans le domaine des télécommunications sans fil, les domaines applicatifs sont de plus en plus larges, s’étendant par exemple du grand public, à la voiture connectée, à l’internet des objets (IoT Internet of Things) et à l’industrie 4.0. Dans ce dernier cas, l’objectif est d’aboutir à une…
