Characterization of the state of a droplet at a micro-textured silicon wafer using a finite difference time-domain (FDTD) method

N.M. Saad, B. Merheb, Georges Nassar, Pierre Campistron, Julien Carlier, M. Ajaka, Bertrand Nongaillard

In this study, we introduce a finite difference time domain method to study the propagation and reflection of an acoustic wave on smooth and micro-textured silicon surfaces in interaction with droplets in different states. This will enable numerical investigations of interfaces composed of…

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:…

Level repulsion and evanescent waves in sonic crystals

V. Romero-Garcia, Jerome O. Vasseur, Anne-Christine Hladky, Lluis Miquel Garcia-Raffi, J.V. Sanchez-Perez

This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The…

The transverse electromagnetic horn antenna as an efficient THz pulse emitter

Jean-Francois Lampin, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau, Jens Klier, Sabine Wohnsiedler, Joachim Jonuscheit, René Beigang

We have fabricated a new photoconductive antenna based on a transverse electromagnetic horn and low temperature grown GaAs. It has been tested with a time-domain terahertz setup. The horn was used as the emitter and a standard dipole photoconductive antenna was used as the receiver. The spectrum…
