Robustness of high-resolution channel parameter estimators in presence of dense multipath components

Emmeric Tanghe, Davy Gaillot, Wout Joseph, M. Lienard, Pierre Degauque, Luc Martens

The estimation accuracy of specular multipath components in radio channels that include dense multipath is investigated. Classical multipath estimation algorithms such as ESPRIT and SAGE do not include dense multipath in their signal model whereas recent ones, such as RiMAX, do. These estimation…

Magnetostatic micro-actuator based on ultrasoft elastomeric membrane and copper-permalloy electrodeposited structures

Jérémy Streque, Abdelkrim Talbi, Clément Bonnerot, Philippe Pernod, Vladimir Preobrazhensky

This paper presents different designs of magnetostatic micro-actuators, based on both conventional and integrated micro-coils. A 3-dimensional magnetic circuit made of Permalloy is proposed in order to improve their efficiency. The mobile parts of the micro-actuators are made of ultrasoft…

Dual-purpose BGaN layers on performance of nitride-based high electron mobility transistors

Vinod Ravindran, Mohamed Boucherit, Ali Soltani, Simon Gautier, Tarik Moudakir, Jeramy Dickerson, Paul L. Voss, Marie-Antoinette Di Forte-Poisson, Jean-Claude de Jaeger, Abdallah Ougazzaden

A GaN/ultrathin BGaN/GaN heterojunction is used in AlGaN/GaN high electron mobility transistors (HEMTs) to provide an electrostatic barrier to electrons and to improve the confinement of the 2-dimensional electron gas. BGaN back-barrier layers limit leakage in the GaN buffer thanks to two effects:…

Interplay between Sb flux and growth temperature during the formation of GaSb islands on GaP

S. El Kazzi, L. Desplanque, X. Wallart, Y. Wang, P. Ruterana

We investigate the influence of the Sb flux on the growth of GaSb islands on a highly mismatched (001) GaP substrate. Between low and medium Sb flux values, standard kinetics drives the GaSb island formation and their relaxation is progressively favored by 90° misfit dislocations at the GaSb/GaP…

Optimization of electrodes design for PZT thin-film actuated membranes

F. Casset, H. Michaud, T. Ricart, G. Le Rhun, M. Cueff, J. Abergel, P. Ancey, D. Faralli, Arnaud Devos, S. Fanget, E. Defay

This paper reports on the optimization of electrodes design for sol-gel Pb(Zr0.52, Ti0.48)O3 (PZT) thin-film actuated-membranes. PZT can be used in many actuator applications such as micro mirror, RF MEMS, inkjet or loudspeaker due to its strong piezoelectric properties. We aim to design membrane-…
