The limits of edge bead planarization and surface levelling in spin-coated liquid films

S. Arscott

A model is presented here to predict fluid reflow in a viscous liquid film having time-dependent physical properties. The model is applied to the practical example of the reflow planarization (surface levelling) of 'edge bead' features resulting from the spin coating process. During the…

Power Domain NOMA Without SIC in Downlink CSS-Based LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Ido Nevat, Laurent Clavier

Low Power Wide Area Network, such as LoRa is one of the main building blocks of the Internet of Things. One of the main issues is to scale up the number of devices and one strong limitation comes from the downlink communication. In fact, the access point is constrained by the duty cycle, therefore…

Full-duplex relaying for opportunistic spectrum access under an overall power constraint

Anne Savard, Elena Veronica Belmega

To meet the bold requirements of future generation networks, emerging technologies such as opportunistic spectrum access, multi-tier networks, full-duplexing and cooperative networks have to be exploited. In this paper, we propose to blend all the above and globally optimize a relay-aided cognitive…

Electrothermal modeling of GaN power transistor for high frequency power converter design

Loris Pace, Florian Chevalier, Arnaud Videt, N. Defrance, Nadir Idir, Jean-Claude de Jaeger

This work proposes the electrothermal modeling of a packaged GaN power transistor in order to evaluate by simulation its performances in a 200 W - 1 MHz DC/DC converter. The complete electrical modeling of the high frequency converter using EM-circuit co-simulations is presented. After validation…

Wireless communication using ultrasonic guided waves in healthy and defected plates

Rudy Bahouth, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

Transmission of digital data in solid structures is effective in many industrial applications such as nuclear, aerospace and smart vehicles. Traditional wireless communication using electromagnetic waves becomes ineffective in the presence of metals due to Faraday shielding. Ultrasonic guided waves…

[Invited] Miniaturisation du stockage électrochimique de l'énergie : vers la fabrication de micro-batteries performantes tout solide

Christophe Lethien

La miniaturisation des objets connectés impose la fabrication de sources de stockage d’énergie de plus en plus petites. A ce titre, la fabrication de batteries miniatures tout solide (appelées micro-batteries) performantes est un challenge scientifique où la tendance est de passer d’une technologie…
