We extend time-domain imaging in acoustic metamaterials to gigahertz frequencies. Using a sample consisting of a regular array of ∼1 μ m diameter silica microspheres forming a two-dimensional triangular lattice on a substrate, we implement an ultr

Picosecond acoustic interferometry is used to monitor in time the motion of the phase transition boundary between two water ice phases, VII and VI, coexisting at a pressure of 2.15 GPa when compressed in a diamond anvil cell at room temperature. By a

We present an acoustic metamaterial for flexural waves with both negative density and elastic modulus. By means of an analytical lumped-element approach, we introduce a combination of resonant elements on the surface of a plate. Following on from exp

Using an ultrafast optical technique we image near-gigahertz flexural acoustic waves propagating in a thin gold wedge deposited on an ultrathin silicon nitride slab. Temporal Fourier transforms of the imaged data in two dimensions allow individual fr

Most of the energy harvesting principles are realized in heated-continuously systems. Here, the authors present a concept of high-frequency energy harvesting where the dissipated heat in a sample excites resonant magnons in a ferromagnetic metal laye

Optically generated acoustic phonons have enabled depth resolved microstructure characterization. Here, the authors extend this method to obtain information on the orientation of individual crystallites by studying influence of probe beam polarizatio

We applied time-domain Brillouin scattering (TDBS) for the characterization of porogen-based organosilicate glass (OGS) films deposited by spin-on-glass technology and cured under different conditions. Although the chemical composition and porosity m

Electrically driven acousto-optic light modulators are limited to frequencies of a few hundred megahertz and are typically no smaller than a few micrometres. Here, the authors demonstrate gigahertz acousto-optic conversion of light polarization in a
