Optimization of PZT ceramic IDT sensors for health monitoring of structures

Rafatou Takpara, Marc Duquennoy, Mohammadi Ouaftouh, Christian Courtois, Frédéric Jenot, Mohamed Rguiti

Surface acoustic waves (SAW) are particularly suited to effectively monitoring and characterizing structural surfaces (condition of the surface, coating, thin layer, micro-cracks…) as their energy is localized on the surface, within approximately one wavelength. Conventionally, in non-destructive…

Dynamic Characterization of III-Nitride-Based High-Speed Photodiodes

Bandar Alshehri, Karim Dogheche, Sofiane Belahsene, Abderrahim Ramdane, Gilles Patriarche, Didier Decoster, El Hadj Dogheche

The objective of this study is to study, design, and develop a high-speed PIN photodiode based on In x Ga 1-x N/GaN alloys deposited by metal-organic chemical vapor deposition. The configuration used for the PIN photodiode is based on an absorbing layer composed of In 0.1 Ga 0.9 N multiple quantum…

A uniform formalism for acoustic wave propagation in a mixed liquid-solid-porous viscoelastic multilayered structure

Sandrine Matta, Wei-Jiang Xu, Georges Nassar, Antoine Abche

To deepen the understanding of the ultrasonic behaviour of human multi-layered bone tissues, cortical bone for example, the reflection and transmission of ultrasonic wave at such a structure consisting of a combination of liquid-solid-porous layers was studied. A mathematical model for the plane…

Impact of dispersion forces on the atomic structure of a prototypical network-forming disordered system: The case of liquid GeSe2

Évelyne Martin, Assil Bouzid, Guido Ori, Mauro Boero, Carlo Massobrio

A set of structural properties of liquid GeSe2 are calculated by using first-principles molecular dynamics and including, for the first time, van der Waals dispersion forces. None of the numerous atomic-scale simulations performed in the past on this prototypical disordered network-forming material…
