GaN RF and power research at IEMN

F Medjdoub

GaN high electron mobility transistors (HEMT) are becoming the mainstream for high frequency and power switching applications. Devices and circuits based on these emerging materials are more suited to operate at higher voltages and temperatures than Si-based devices owing to their superior physical…

Silicon nanowire-hydrogenated TiO2 core-shell arrays for stable electrochemical micro-capacitors

Yasmina Bencheikh, Ahmed Addad, Yannick Coffinier, Umesh Kumar, Pascal Roussel, Sabine Szunerits, Toufik Hadjersi, Mohammed Amin, Seddik El Hak Abaidia, Rabah Boukherroub

In this paper, we fabricated silicon nanowire-TiO2 core-shell arrays in a two-step process. First, silicon nanowire arrays (SiNW) were prepared in HF/AgNO3 aqueous solution using metal-assisted chemical etching of bulk silicon. Then, atomic layer deposition (ALD) technique was applied to coat a 20…

Fortran Package Manager: Toward a rich ecosystem of Fortran packages

Sebastian Ehlert, Ondřej Čertík, Milan Curcic, Jakub Jelínek, Laurence Kedward, Vincent Magnin, Emanuele Pagone, Brad Richardson, John Urban

Fortran is the oldest programming language still in use today, targeting high-performance scientific and engineering applications. Traditionally, Fortran software has used build systems that are not portable or are difficult to use or extend. This has presented a significant barrier to entry for…

Periodic Structures, Irreducible Brillouin Zone, Dispersion Relations and the Plane Wave Expansion Method

Jerome O. Vasseur

The Plane Wave Expansion (PWE) method allows the calculation of dispersion curves, i.e., the relation linking the frequency to the wave number for any propagating mode of periodic structures made of elastic materials such as phononic crystals. The method is relatively easy to implement numerically…

An Analytical Model of the End-to-End Performance for Linear Video Delivery Under Bandwidth Constraints

Anthony Trioux, M Gharbi, François-Xavier Coudoux, Patrick Corlay

Recently, Linear Video Coding and Transmission (LVCT) schemes have been proposed as an alternative to traditional video transmission schemes, the latter experiencing cliff-effect [3] in wireless error-prone environments. In this paper, we propose an analytical model to estimate/predict the end-to-…

Optimization of spider web-inspired phononic crystals to achieve tailored dispersion for diverse objectives

Vinícius F Dal Poggetto, Federico Bosia, M. Miniaci, Nicola M Pugno

Spider orb webs are versatile multifunctional structures with optimized mechanical properties for prey capture, but also for transmitting vibrations. The versatility of such a system mainly derives from its variable geometry, which can be effectively used to design phononic crystals, thus…

Study of Electrode Locations for Joint Acquisition of Impedance- and Electro-cardiography Signals

Margus Metshein, Antoine Gautier, Benoit Larras, Antoine Frappé, Deepu John, Barry Cardiff, Paul Annus, Raul Land, Olev Martens

ICG (impedance cardiography) and ECG (electrocardiography) provide important indications about functioning of the heart and of overall cardiovascular system. Measuring ICG along with ECG using wearable devices will improve the quality of health monitoring, as ICG points to important hemodynamic…
