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 ...

Pulse mode shear horizontal-surface acoustic wave (SH-SAW) system for liquid based sensing applications

, 2004
In this work, we describe a novel pulse mode shear horizontal-surface acoustic wave (SH-SAW) polymer coated biosensor that monitors rapid changes in both amplitude and phase.

From Microwave Acoustic Filters to Millimeter-Wave Operation and New Applications

IEEE Journal of Microwaves, 2023
This paper reviews the latest developments in microwave acoustic wave devices. After an introduction and brief history of bulk acoustic wave (BAW) and surface acoustic wave (SAW) devices, a review is given for guided SAWs and XBARs - two new technologies,

Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension [PDF]

, 2009
Aims: We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations ...

Acoustic properties of La3Ga5.3Ta0.5Al0.2O14 crystal

Modern Electronic Materials, 2015
Development and search for new advanced materials of the lanthanum gallium silicate group with unique thermal properties is of great importance for the development of acoustoelectronics based on volume and surface acoustic waves. The processes of surface

ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers

, 2008
We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used

Acoustic radiation from a pulsating spherical cap set on a spherical baffle near a hard/soft flat surface

, 2004
Radiation of sound from a spherical piston, set in the side of a rigid sphere, undergoing harmonic radial surface vibrations in an acoustic halfspace is analyzed in an exact fashion using the classical method of separation of variables.

Surface Acoustic Wave (SAW) Vibration Sensors

Sensors, 2011
In the paper a feasibility study on the use of surface acoustic wave (SAW) vibration sensors for electronic warning systems is presented. The system is assembled from concatenated SAW vibration sensors based on a SAW delay line manufactured on a surface ...

Mass sensitivity of acoustic wave devices from group and phase velocity measurements [PDF]

, 2002
The effect of dispersion on acoustic wave sensors is considered. The discussion is focused upon layer guided surface acoustic waves (Love waves), which obtain their high mass sensitivity for the first Love wave mode by optimizing the guiding layer ...
