In-plane backward and Zero-Group-Velocity guided modes in rigid and soft strips
Jérôme Laurent, Daniel Royer, Claire Prada
Elastic waves guided along bars of rectangular cross section exhibit complex dispersion. This paper studies in-plane modes propagating at low frequencies in thin isotropic rectangu…
Imaging Gigahertz Zero-Group-Velocity Lamb Waves
Qingnan Xie, Sylvain Mezil, Paul H Otsuka +5
We image GHz zero-group-velocity (ZGV) Lamb waves in the time domain by means of an ultrafast optical technique, revealing their stationary nature and their acoustic energy localiz…
Negative refraction of Lamb modes: A theoretical study
François Legrand, Benoît Gérardin, Jérôme Laurent +2
This paper provides a theoretical investigation of negative refraction and focusing of elastic guided waves in a free-standing plate with a step-like thickness change. Under certai…
