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...

Unstationary dynamics of drops subjected to MHz-surface acoustic waves modulated at low frequency

Philippe Brunet, Michael Baudoin

In the present work, we investigate the unstationary dynamics of sessile droplets subjected to high-frequency surface acoustic waves modulated at a lower frequency close to the first inertio-capillary resonance mode of the drop. Under the action of both acoustic streaming and radiation pressure,...

High Breakdown Field and Low Trapping Effects up to 1400 V in Normally Off GaN‐on‐Silicon Heterostructures

Idriss Abid, Youssef Hamdaoui, Jash Mehta, F Medjdoub

In this study, we report on the development of a fully normally-off high electron mobility transistor (HEMT) gallium nitride on silicon (GaN-on-Si) heterostructures designed for high voltage operation. The normally-off configuration was achieved by means of a p-gallium nitride (p-GaN) cap layer...

CRC-Based Correction of Multiple Errors Using an Optimized Lookup Table

Vivien Boussard, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

In this paper, we propose a new approach to perform multiple error correction in wireless communications over error-prone networks. It is based on the cyclic redundancy check syndrome, using an optimized lookup table that avoids performing arithmetic operations. This method is able to achieve the...

Elaboration and characterization of porous ultrathin gold films grown by ion beam assisted deposition

Abdelhanin Aassime, Marc Duquennoy, Frédéric Hamouda, Tahar Kadi, Frédéric Mahut, Mohammadi Ouaftouh

The growth of ultrathin gold layers on a silicon substrate is performed with an unconventional ion beam assisted deposition. In this setup, evaporated gold flow and ion beam flux are perpendicular. 5 and 10 nm thick gold were deposited on tilted samples with the assistance of an argon ion beam at...

Can classical surface plasmon resonance advance via the coupling to other analytical approaches?

David Geilfuss, Rabah Boukherroub, Jakub Dostalek, Wolfgang Knoll, Jean-Francois Masson, Antje Baeumner, Sabine Szunerits

For nearly 40 years, surface plasmon resonance (SPR) analysis has been used to better understand the binding interaction strength between surface immobilized bioreceptors and the analytes of interest. The advantage of surface plasmon resonance, over other affinity sensing approaches such as Western...

Nanostructures wetting evaluation using ultra high frequency ultrasound

Abbas Salhab, Julien Carlier, Malika Toubal, Pierre Campistron, Marc Neyens, Bertrand Nongaillard, V. Thomy

Ultrasounds are a great tool for defects detection particularly for optically non-transparent materials. Hence, working at very high frequency (#GHz) allows the detection of nanoscale contact defects at the interface between two materials and especially in the presence of air, which has negligible...
