Journal ArticleDOI
Low-frequency gaps in a phononic crystal constituted of cylindrical dots deposited on a thin homogeneous plate
Yan Pennec,Bahram Djafari-Rouhani,H. Larabi,Jérôme Olivier Vasseur,Anne-Christine Hladky-Hennion +4 more
TL;DR: In this paper, the authors investigate the band structure of a phononic crystal of finite thickness constituted of a periodical array of cylindrical dots deposited on a thin plate of a homogeneous material and show that this structure can display a low-frequency gap, as compared to the acoustic wavelengths in the constituent materials.
Journal ArticleDOI
Absolute forbidden bands and waveguiding in two-dimensional phononic crystal plates
Jérôme Olivier Vasseur,Pierre A. Deymier,Bahram Djafari-Rouhani,Yan Pennec,Anne-Christine Hladky-Hennion +4 more
TL;DR: In this paper, a supercell plane wave expansion (SC-PWE) method was proposed for the calculation of elastic band structures of two-dimensional phononic crystal plates. But the method suffers from convergence difficulties.
Journal ArticleDOI
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.

Analysis of the propagation of plane acoustic waves in passive periodic materials using the finite element method
TL;DR: In this paper, Hladky-Hennion et al. presented a new extension of the finite element approach to the analysis of the propagation of plane acoustic waves in passive periodic materials without losses and described its application to doubly periodic materials containing different types of inclusions.
