Combined UTC-PD integrated on-chip THz near field microscopy with coupled planar Goubau lines

Tahsin Akalin, Abdallah Chahadih, Abbas Ghaddar, Ibrahim Tirer

In most of the cases for terahertz near field microscopy, a free space propagating electromagnetic wave interacts with a small tip placed above the sample. In our original approach, we use a guided way to bring the terahertz wave and to improve the interaction efficiency with the sample. The idea...

The Non-Ideal Organic Electrochemical Transistors Impedance

Sébastien Pecqueur, Ivor Lončaric, Vinko Zlatić, Dominique Vuillaume, Željko Crljen

Organic electrochemical transistors offer powerful functionalities for biosensors and neuroinspired electronics, with still much to understand on the time dependent behavior of this electrochemical device. Here, we report on distributed element modeling of the impedance of such microfabricated...

A Multiscale Numerical Model for Structures with Internal Frictional Contacts

Kevin Truyaert, Vladislav Aleshin, Steven Delrue, Koen van den Abeele

Abstract Many engineering applications are related to or deal with materials and systems having internal frictional contacts in their structure. The effects induced by these contacts, such as friction-induced heat generation, wear, nonlinear vibrations, etc., can be significant and cannot be...

Hyperfine Interactions and Slow Spin Dynamics in Quasi-isotropic InP-based Core/Shell Colloidal Nanocrystals

Annalisa Brodu, Mickaël Tessier, Damien Canneson, Dorian Dupont, Mariana V Ballottin, Peter C M Christianen, Celso de Mello Donega, Zeger Hens, Dmitri R Yakovlev, Manfred Bayer, Daniel Vanmaekelbergh, Louis Biadala

Colloidal InP core/sell nanocrystals are taking over CdSe-based nanocrystals, notably in optoelectronic applications. Despite their use in commercial device such as display screens, the optical properties of InP nanocrystals and especially their relation with the exciton fine structure remains...

Canal à deux relais utilisant Compress-and-Forward

Anne Savard, Laurent Clavier

Ce papier propose une étude d'un canal bi-directionnel où deux relais aident deux utilisateurs à échanger leurs données. Nous nous concentrons sur le cas où l'un des deux relais utilise le schéma Compress-and-Forward (CF) alors que l'autre relais peut utiliser soit CF soit Decode-and...

Méthodes de prétraitement pour les systèmes de codage vidéo linéaire basé SoftCast

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

Un nouveau schéma de codage vidéo linéaire dénommé SoftCast a démontré ces dernières années un potentiel élevé pour la diffusion de vidéo sur des canaux sans-fil variant dans le temps. Particulièrement utile en situation de broadcast, il permet d’éviter les problèmes rencontrés dans les systèmes de..., An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encounteredin conventional wireless video broadcasting systems such as cliff effect [1]. In [2], we analyzed and compared two simple pixel-preprocessing methods that help to increase...
