Covert Capacity of Non-Coherent Rayleigh-Fading Channels

Mehrdad Tahmasbi, Anne Savard, Matthieu Bloch

The covert capacity is characterized for a non-coherent fast Rayleigh-fading wireless channel, in which a legitimate user wishes to communicate reliably with a legitimate receiver while escaping detection from a warden. It is shown that the covert capacity is achieved with an amplitude-constrained…

Surface spin magnetism controls the polarized exciton emission from CdSe nanoplatelets

Elena V Shornikova, Aleksandr A Golovatenko, Dmitri R Yakovlev, Anna V Rodina, Louis Biadala, Gang Qiang, Alexis Kuntzmann, Michel Nasilowski, Benoit Dubertret, Anatolii Polovitsyn, Iwan Moreels, Manfred Bayer

The surface of nominally diamagnetic colloidal CdSe nanoplatelets can demonstrate para-magnetism owing to the uncompensated spins of dangling bonds (DBSs). We reveal that by optical spectroscopy in high magnetic fields up to 15 Tesla using the exciton spin as probe of the surface magnetism. The…

Temperature compensated magnetic field sensor based on Love waves

Harshad Mishra, Jérémy Streque, Michel Hehn, Prince Mengue, Hamid M'Jahed, Daniel Lacour, Karine Dumesnil, S. Petit-Watelot, Sergei Zhgoon, Vincent Polewczyk, Aurélien Mazzamurro, Abdelkrim Talbi, Sami Hage-Ali, Omar Elmazria

A temperature compensated magnetic field sensor based on the combination of CoFeB ferromagnetic thin films and Quartz/ZnO Love waveguide platform is developed and optimized. The Love wave is a shear horizontal guided wave and therefore provides an optimal interaction with magnetisation in the…

Unravelling local environments in mixed TiO2–SiO2 thin films by XPS and ab initio calculations

Pavel Ondračka, David Nečas, Michèle Carette, Stéphane Elisabeth, David Holec, Agnès A. Granier, Antoine Goullet, Lenka Zajíčková, Mireille Richard-Plouet

Mixed TixSi1−xO2 oxide can exhibit a partial phase separation of the TiO2 and SiO2 phases at the atomic level. The quantification of TiO2-SiO2 mixing in the amorphous material is complicated and was so far done mostly by infrared spectroscopy. We developed a new approach to the fitting of X-ray…

Giant Magnetoelastic Coupling in a Love Acoustic Waveguide Based on TbCo 2 /FeCo Nanostructured Film on ST-Cut Quartz

Aurélien Mazzamurro, Yannick Dusch, Philippe Pernod, Olivier Bou Matar, Ahmed Addad, Abdelkrim Talbi, Nicolas Tiercelin

In this work, we propose a theoretical and experimental investigation of the interaction of guided pure shear horizontal (SH) wave within a uniaxial multilayered TbCo2/FeCo thin film deposited on Quartz ST-90°X cut in a delay line configuration. We evaluate theoretically the evolution of phase…

Cross-Layer CNN Approximations for Hardware Implementation

Karim Mohamed Abedallah Ali, Ihsen Alouani, Abdessamad Ait El Cadi, Hamza Ouarnoughi, Smail Niar

Convolution Neural Networks (CNNs) are widely used for image classification and object detection applications. The deployment of these architectures in embedded applications is a great challenge. This challenge arises from CNNs’ high computation complexity that is required to be implemented on…

Emulation of various radio access technologies for zero on site testing in the railway domain - the Emulradio4rail platforms

Marion Berbineau, Juan Moreno, Sofiane Kharbech, Ying Yang, Alessandro Vizzari, Raul Torrego, José Soler, Laurent Clavier, Rédha Kassi, Franco Mazzenga, Romeo Giuliano, Val Inaki, Christophe Gransart, Virginie Deniau, Yann Cocheril, Kristina Svensson, Armano Carillo

In order to assess the reliability, availability, and maintainability of wireless links for the rail sector in the laboratory, it is necessary to develop measurement platforms able to emulate real railway radio environments. This type of testing platform should combine very new approaches, the so-…

A fully-integrated high-isolation transfer switch for G-band in-situ reflectometer applications

Walid Aouimeur, Marc Margalef-Rovira, Estelle Lauga-Larroze, Daniel Gloria, Christophe Gaquière, Issa Alaji, Jean-Daniel Arnould

This paper describes two fully-integrated transfer switches designed for in-situ reflectometers and Built-In Self-Test applications (BIST) in the 140 to 220 GHz band (G-band). The proposed switches were designed in the STMicroelectronics 55-nm BiCMOS technology using the Single-Shunt and the Double…

Multibias and temperature dependence of the current-gain peak in GaN HEMT

Mohammad A. Alim, Muhammad A. Hasan, Ali A. Rezazadeh, Christophe Gaquière, Giovanni Crupi

Thermal and multibias behavior of the peak in the short-circuit current-gain (h21) has been investigated for a GaN HEMT, aiming to contribute to an extensive knowledge on it. To obtain a simple and complete insight of this phenomenon and its influence in device performance over operating conditions…
