Acoustic radiation pressure for nonreciprocal transmission and switch effects

Here, the authors experimentally report one-way transmission of ultrasonic waves by relying on the acoustic radiation pressure effect. This effect makes it possible to reconfigure a multilayer system by significantly deforming the water-air interface, achieving efficient nonreciprocal acoustic transmission.

Phase transitions in 2D multistable mechanical metamaterials via collisions of soliton-like pulses

In high-dimensional multistable mechanical metamaterials, phase transitions can be remotely nucleated and controlled via collisions of nonlinear pulses, potentially bringing new insights for the design of reconfigurable structures.

Imaging grain microstructure in a model ceramic energy material with optically generated coherent acoustic phonons

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 polarization on detected signal amplitude.
