Tunable magnetoelastic phononic crystals
Jean-François Robillard,Jean-François Robillard,O. Bou Matar,O. Bou Matar,J. O. Vasseur,Pierre A. Deymier,M. Stippinger,M. Stippinger,Anne-Christine Hladky-Hennion,Yan Pennec,Bahram Djafari-Rouhani +10 more
TL;DR: In this article, the feasibility of tuning the band structure of phononic crystals is demonstrated by employing magnetostrictive materials and applying an external magnetic field, and the authors show the contactless tunability of the absolute band gaps of a two-dimensional phononic crystal composed of an epoxy matrix and Terfenol-D inclusions.

Journal ArticleDOI
Complete thin film mechanical characterization using picosecond ultrasonics and nanostructured transducers: experimental demonstration on SiO2
TL;DR: In this article, the authors performed complete mechanical measurements in submicron films using the picosecond ultrasonic technique, where the Al layer deposited on the top of the sample acting as a transducer was replaced with a nanostructured Al film.
