Cloaking, Trapping and Superlensing of Lamb Waves with Negative Refraction
François Legrand, Benoît Gérardin, François Bruno +4
We report on experimental and numerical implementations of devices based on the negative refraction of elastic guided waves, the so-called Lamb waves. Consisting in plates of varyi…
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…
Multiple scattering of ultrasound in weakly inhomogeneous media: application to human soft tissues
Alexandre Aubry, Arnaud Derode
Waves scattered by a weakly inhomogeneous random medium contain a predominant single scattering contribution as well as a multiple scattering contribution which is usually neglecte…
Detection and imaging in a random medium: A matrix method to overcome multiple scattering and aberration
Alexandre Aubry, Arnaud Derode
We present an imaging technique particularly suited to the detection of a target embedded in a strongly scattering medium. Classical imaging techniques based on the Born approximat…
Singular value distribution of the propagation matrix in random scattering media
Alexandre Aubry, Arnaud Derode
The distribution of singular values of the propagation operator in a random medium is investigated, in a backscattering configuration. Experiments are carried out with pulsed ultra…
