We propose a novel class of acoustic metamaterial for low-frequency broadband sound
absorption with high efficiency. The design principle is physically decoupled into low …

Laser ultrasonic technique has been increasingly implemented for nondestructive testing
and structural health monitoring. However, the poor signal-to-noise ratio (SNR) and low …

Time-domain Brillouin scattering (TDBS) is a developing technique for imaging/evaluation of
materials, currently used in material science and biology. Three-dimensional imaging and …

Microstructural mapping of polycrystalline metallic alloys is a key component in predicting
macroscopic material behavior, and non-destructive subsurface polycrystalline imaging is a …

Acoustic properties of buried graphitized layers in diamond formed by ion implantation
followed by annealing were studied using the picosecond ultrasonic technique with spatial …

We present a picosecond optoacoustic technique for mapping both the longitudinal sound
velocity v and the refractive index n in solids by automated measurement at multiple probe …

Picosecond acoustics is an optical pump-probe technique allowing to access thermoelastic
properties and sound velocities of a large variety of materials under extreme conditions …

Acoustic imaging techniques are powerful, nondestructive tools used to perform elastic
imaging of systems. Acoustic imaging techniques have a large variety of applications in both …

In this paper, we demonstrate for the first time the focusing of gigahertz coherent phonon
pulses propagating in water using picosecond ultrasonics and Brillouin light scattering. We …
