Laser array line source with adjustable period used for LGUS chemical corrosion detection

Journal of Saudi Chemical Society, 2022
A novel optical arrangement to generate a laser array line source of laser-generated ultrasound based on two-beam interference is proposed. The arrangement simplifies the adjustment of the laser array source period by changing the intersection angle of ...

Single-electron transport driven by surface acoustic waves: moving quantum dots versus short barriers

, 2006
We have investigated the response of the acoustoelectric current driven by a surface-acoustic wave through a quantum point contact in the closed-channel regime.

A Parametric Study of the Acoustic Mechanism for Core-Collapse Supernovae [PDF]

, 2017
We investigate the criterion for the acoustic mechanism to work successfully in core-collapse supernovae. The acoustic mechanism is an alternative to the neutrino-heating mechanism.

Phased electromagnetic acoustic transducer array for Rayleigh wave surface defect detection [PDF]

, 2020
A phased electromagnetic acoustic transducer (EMAT) array system has been developed for detection and characterisation of surface breaking defects. An array of four linear coils which are individually controlled are used to generate a Rayleigh wave.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Study of “acoustic tweezer” chip for particles driving

MATEC Web of Conferences, 2017
Surface Acoustic Wave (SAW) is one of the sound waves that travel parallel to the surface of an elastic material, and is capable of manipulating microparticles. This SAW device was named acoustic tweezers.
