Time reversed acoustics techniques for elastic imaging in reverberant and nonreverberant media : an experimental study of the chaotic cavity transducer concept

B. van Damme, K. van den Abeele, Y.F. Li, Olivier Bou Matar

In view of emerging imaging technologies based on the combination of Time Reversed Acoustics (TRA) with Nonlinear Elastic Wave Spectroscopy (NEWS) for the detection and localization of micro-damage in solids, we have investigated the benefits of chirped source signal excitation, inverse filtering…

Magnetic field modulated dielectric relaxation behavior of Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 heterostructure in metal-insulator transition region : an equivalent-circuit method

J.Y. Zhu, J. Yang, W. Bai, C.G. Duan, S. Zhang, G.S. Wang, X.L. Dong, Denis Remiens, X.D. Tang

Utilizing temperature and magnetic field dependent dielectric spectroscopy, two different dielectric relaxation processes, both accompanied with prominent positive magnetodielectric (MD) effects, were observed in Pt/BiScO3-PbTiO3/La0.7Sr0.3MnO3 (Pt/BSPT/LSMO) heterostructure. An equivalent circuit…

Milliwatt-level output power in the sub-terahertz range generated by photomixing in a GaAs photoconductor

Emilien Peytavit, Sylvie Lepilliet, Francis Hindle, Christophe Coinon, Tahsin Akalin, Guillaume Ducournau, Gaël Mouret, Jean-Francois Lampin

It is shown from accurate on-wafer measurement that continuous wave output powers of 1.2 mW at 50 GHz and 0.35 mW at 305 GHz can be generated by photomixing in a low temperature grown GaAs photoconductor using a metallic mirror Fabry-Pérot cavity. The output power is improved by a factor of about…

Tunability of aluminum nitride acoustic resonators: a phenomenological approach

Emmanuel Defay, Nizar Ben Hassine, Patrick Emery, Guy Parat, Julie Abergel, Arnaud Devos

A phenomenological approach is developed to identify the physical parameters causing the dc-voltage-induced tunability of aluminum nitride (AlN) acoustic resonators, widely used for RF filters. The typical resonance frequency of these resonators varies from 2.038 GHz at -200 V to 2.062 GHz at +200…

Atomic scale investigation of silicon nanowires and nanoclusters

Manuel Roussel, W.H. Chen, Etienne Talbot, Rodrigue Lardé, E. Cadel, F. Gourbilleau, B. Grandidier, D. Stievenard, Philippe Pareige

In this study, we have performed nanoscale characterization of Si-clusters and Si-nanowires with a laser-assisted tomographic atom probe. Intrinsic and p-type silicon nanowires (SiNWs) are elaborated by chemical vapor deposition method using gold as catalyst, silane as silicon precursor, and…
