Broadband sound shielding of Lamb waves through a periodic array of junctions

R.P. Moiseyenko, Yan Pennec, R. Marchal, B. Bonello, Bahram Djafari-Rouhani

We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a…

Transverse acoustic waves in piezoelectric-metallic Fibonacci multilayers

M. Alami, I. Quotane, E.H. El Boudouti, Bahram Djafari-Rouhani

We study the propagation of transverse acoustic waves in quasi-periodic structures following the Fibonacci sequence made of two blocs A and B where the block A is a metal layer and the bloc B is a piezoelectric layer. The phonon dynamics is described by coupled elastic equations within the static…
