Simultaneous Recovery of Dielectric Constants, Photoelastic Constants, and Strain Profiles from Picosecond Ultrasonic Echoes
Richard Wiltshaw, Motonobu Tomoda, Osamu Matsuda +3
Light reflected from a deforming solid depends on boundary motion and strain-induced modulation of the dielectric response. For a propagating acoustic field, scattering from differ…
Imaging Gigahertz Zero-Group-Velocity Lamb Waves
Qingnan Xie, Sylvain Mezil, Paul H Otsuka +5
We image GHz zero-group-velocity (ZGV) Lamb waves in the time domain by means of an ultrafast optical technique, revealing their stationary nature and their acoustic energy localiz…
Gigahertz optomechanical modulation by split-ring-resonator nanophotonic meta-atom arrays
Y. Imade, R. Ulbricht, M. Tomoda +4
Using polarization-resolved transient reflection spectroscopy, we investigate the ultrafast modulation of light interacting with a metasurface consisting of coherently vibrating na…
Origin of Negative Density and Modulus in Acoustic Metamaterials
Sam Hyeon Lee, Oliver B. Wright
This paper provides a review and fundamental physical interpretation for the effective densities and moduli of acoustic metamaterials. We introduce the terminology of hidden force…
