La photonique dans la métropole lilloise

Laurent Bigot, Guillaume Ducournau, A. Amo

Ces dernières années, la métropole lilloise s’est imposée comme un pôle de recherche académique incontournable dans le domaine de la photonique. C’est notamment le cas des travaux en optique fibrée, en optique non-linéaire, en topologie ou encore en photonique-Terahertz, qui ont une forte…

How to tame a free non-laminar Savart sheet into individual jets?

Sofiene Oulded Taled Salah, Ghada Chouk, Alexis Duchesne, Nicolas de Cock, Khaoula Abrougui, Frédéric Lebeau, Stéphane Dorbolo

In this article, we study the division of a non-laminar Savart sheet into individual jets by mean of local disturbances. We paint a precise portrait of a free non-laminar Savart sheet formed by the vertical impact of a jet on a horizontal disk, its evolution in the air and its break up. We then…

Embroidered Spoof Surface Plasmon Polariton Transmission Line for Wireless Body Sensor Network

Ali Ghaddar, Baptiste Garnier, François Rault, Eric Lheurette, Ludovic Burgnies

A wearable Spoof Surface Plasmon Polariton Transmission Line (SSPP TL) operating at 2.45 GHz designed for embroidery production and on-body communication is proposed. The SSPP TL supports both even and odd modes launched by near field coupling with a dipole antenna perpendicular and parallel to the…

Low Buffer Trapping Effects above 1200 V in Normally off GaN-on-Silicon Field Effect Transistors

Idriss Abid, Youssef Hamdaoui, Jash Mehta, Joff Derluyn, Farid Medjdoub

We report on the fabrication and electrical characterization of AlGaN/GaN normally off transistors on silicon designed for high-voltage operation. The normally off configuration was achieved with a p-gallium nitride (p-GaN) cap layer below the gate, enabling a positive threshold voltage higher than…

Load-Pull Setup Development at 185 GHz for On-Wafer Characterization of SiGe HBT in BiCMOS 55 nm Technology

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Marc Margalef-Rovira, Issa Alaji, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article aims to discuss challenges and performances of a passive load-pull test bench dedicated to the G-band frequencies. The first task of this work is the development of the setup to perform high power generation, impedance generation, and high-power dynamic of measurement. The solution…

Towards Outdoor Electromagnetic Field Exposure Mapping Generation Using Conditional GANs

Mohammed Mallik, Angesom Ataklity Tesfay, Benjamin Allaert, Rédha Kassi, Esteban Egea-Lopez, Jose-Maria Molina-Garcia-Pardo, Joe Wiart, Davy Gaillot, Laurent Clavier

With the ongoing fifth-generation cellular network (5G) deployment, electromagnetic field exposure has become a critical concern. However, measurements are scarce, and accurate electromagnetic field reconstruction in a geographic region remains challenging. This work proposes a conditional…

Review on Unmanned Aerial Vehicle Assisted Sensor Node Localization in Wireless Networks: Soft Computing Approaches

Visalakshi Annepu, Deepika Rani Sona, Chinthaginjala Ravikumar, Kalapraveen Bagadi, Mohammad Alibakhshikenari, Ayman Althuwayb, Bader Alali, Bal Virdee, Giovanni Pau, Iyad Dayoub, Chan Hwang See, Francisco Falcone

Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using fixed terrestrial anchor node (FTAN) because of low implementation complexity…

Modeling of access resistances and channel temperature estimation for GaN HEMT

Shariful Islam, Mohammad Abdul Alim, Abu Zahed Chowdhury, Christophe Gaquière

Accurate prediction of resistances at the transistor’s access zone and their temperature dependency are very important, since the current flow to the device depends on that region. In this paper, we have modeled the access resistances and have verified their temperature dependency with the…

Non-Hermitian skin effect in a phononic beam based on piezoelectric feedback control

Yabin Jin, Wenxin Zhong, Runcheng Cai, Xiaoying Zhuang, Yan Pennec, Bahram Djafari-Rouhani

Non-Hermitian systems have gained a great deal of interest in various wave problems due their ability of exhibiting unprecedented phenomena such as invisibility, cloaking, enhanced sensing, or the skin effect. The latter manifests itself by the localization of all bulk modes in a specific frequency…
