Acoustic excitations and coherent oscillations in macroscopic solid-state structures
Journal of Physics D: Applied PhysicsAbstract The propagation of acoustic waves in steel tendons is investigated within the framework of research for non-invasive localisation of defects in metal structures embedded in concrete. The possibility of determining the status and quality of the structures and, eventually, localising defects in them is demonstrated in both the ...

Topology‐Orchestrated Multi‐physical Energy Control in Turtle Shell‐Inspired Metamaterials
Advanced Materials, EarlyView.A turtle shell‐inspired lattice metamaterial efficiently manages acoustic, fluid‐thermal, and mechanical energy flows simultaneously. The unique hybrid‐coupling architecture achieves superior sound attenuation via pore‐cavity resonance, facilitates effective airflow transport, and maximizes mechanical energy absorption through multistage cell ...

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2
Advanced Materials, EarlyView.Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...
