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…

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…

Passive guided wave tomography for structural health monitoring

Tom Druet, Arnaud Recoquillay, Bastien Chapuis, Emmanuel Moulin

In this paper is presented a baseline-free quantitative method for imaging corrosion flaws in thin plates. It only requires an embedded guided wave sensor network used in a fully passive way, i.e. without active emission of waves. This method is called passive guided waves to-mography. The aim of…

High Lateral Breakdown Voltage in Thin Channel AlGaN/GaN High Electron Mobility Transistors on AlN/Sapphire Templates

Idriss Abid, Riad Kabouche, Catherine Bougerol, Julien Pernot, Cédric Masante, Rémi Comyn, Yvon Cordier, F Medjdoub

In this paper, we present the fabrication and Direct Current/high voltage characterizations of AlN-based thin and thick channel AlGaN/GaN heterostructures that are regrown by molecular beam epitaxy on AlN/sapphire. A very high lateral breakdown voltage above 10 kV was observed on the thin channel…

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…
