Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

Coda wave interferometry (CWI) is a nondestructive evaluation technique for monitoring
wave velocity changes in a strongly heterogeneous medium as demonstrated in previous …

Calcium carbonate biomineralization is a bio-chemical process in which calcium carbonate
precipitation is obtained by leveraging the metabolic activity of microorganisms. Studies …

Experimental measurements of the coherent wave transmission for ultrasonic waves
propagating in water through a random set of scatterers (metallic rods) are presented …

Acoustic wavelengths in soils range from meters to millimeters, depending on their
frequencies. The spatial and temporal scales of pulse transmission through soils are well …

We present the results of ultrasonic pulse propagation experiments on suspensions of
plastic spherical scatterers immersed in water. This system was selected to study the effects …

Flexural cracks are common in reinforced concrete (RC) beams. At service loads, the tensile
stresses induced by the bending moments cause beam sections to crack, leading to loss of …

In a recent paper, we have shown experimental results of ultrasound wave velocity and
attenuation coefficient measurement in macroscopic suspensions. The experimental method …

This paper presents a combined numerical and experimental study on the diffuse ultrasonic
measurement technique for determining the depth of surface breaking cracks in concrete. A …

We demonstrate experimentally that optical wavefront shaping increases light coupling into
the fundamental diffusion mode of a scattering medium. The total energy density inside a …
