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...

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...

Molecular beam epitaxial growth of multilayer 2D-boron nitride on Ni substrates from borazine and plasma-activated nitrogen

Jawad Hadid, Ivy Colambo, Jose Avila, Aexandre Plaud, Christophe Boyaval, D. Deresmes, Nicolas Nuns, Pavel Dudin, Annick Loiseau, Julien Barjon, Xavier Wallart, Dominique Vignaud

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on polycrystalline and monocrystalline Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. The excess of nitrogen atoms allows to overcome the thickness self-limitation active on...

Rayleigh Modes Generated by Laser-Ultrasonics at the Film-Substrate Interface for the Study of Adhesion

Martin Robin, Meriem Chrifi Alaoui, Frédéric Jenot, Mohammadi Ouaftouh, Marc Duquennoy

Adhesion testing of film-on-substrate structures by surface acoustic waves is a complex issue. Indeed, the fluctuations of some parameters like the film thickness can lead to misinterpretation of the experimental results. Additionally, in laser-ultrasonics, the positions of the generation and...

In-plane InGaAs/Ga(As)Sb nanowire based tunnel junctions grown by selective area molecular beam epitaxy

Alexandre Bucamp, Christophe Coinon, Sylvie Lepilliet, David Troadec, Gilles Patriarche, M Diallo, Vanessa Avramovic, Kamel Haddadi, X. Wallart, L. Desplanque

In-plane InGaAs/Ga(As)Sb heterojunction tunnel diodes are fabricated by selective area molecular beam epitaxy with two different architectures: either radial InGaAs core/Ga(As)Sb shell nanowires or axial InGaAs/GaSb heterojunctions. In the former case, we unveil the impact of strain relaxation and...

Combined surface x-ray diffraction and density functional theory study of the germanene/Al(111)-(7×7) R19.1° structure

K. Zhang, M.C. Hanf, D. Sciacca, Romain Bernard, Yves Borensztein, A. Resta, Yves Garreau, A. Vlad, A. Coati, Isabelle Lefebvre, M. Derivaz, C. Pirri, P. Sonnet, R. Stephan, G. Prévot

Several studies have reported the possible growth of germanene on various metal surfaces. However, the exact structure of the layers formed upon evaporation at or above room temperature remains controversial. In particular, the layers obtained after Ge deposition on Al(111) have been either...

Unsupervised deep learning to solve power allocation problems in cognitive relay networks

Yacine Benatia, Anne Savard, Romain Negrel, Elena Veronica Belmega

In this paper, an unsupervised deep learning approach is proposed to solve the constrained and non-convex Shannon rate maximization problem in a relay-aided cognitive radio network. This network consists of a primary and a secondary user-destination pair and a secondary full-duplex relay performing...
