[Extraction d'énergie vibrationnelle par des isolants phononiques à trois dimensions]
Nous rapportons l'existence de bandes interdites phononiques unidirectionnelles qui peuvent se déployer sur des régions étendues de la zone de Brillouin et peuvent être appliquées au piégeage d'ondes (acoustiques) élastiques dans des structures multicouches tridimensionnelles convenablement conçues. Les isolants phononiques opèrent par transmission asymétrique d'ondes à travers une structure phononique cristallographique présentant une symétrie miroir brisée. Du fait de l'utilisation de matériaux sans perte dans le cristal, le taux d'absorption est considérablement accru quand l'isolant proposé est placé près d'une cellule extractrice d'énergie vibratoire.
We report on the existence of unidirectional phononic band gaps that may span over extended regions of the Brillouin zone and can find application in trapping elastic (acoustic) waves in properly designed multilayered 3D structures. Phononic isolators operate as a result of asymmetrical wave transmission through a slab of a crystallographic phononic structure with broken mirror symmetry. Due to the use of lossless materials in the crystal, the absorption rate is dramatically enhanced when the proposed isolator is placed next to a vibrational harvesting cell.
