Multiple Scattering Formulation of Two Dimensional Acoustic and Electromagnetic Metamaterials [PDF]
This work presents a multiple scattering formulation of two dimensional acoustic metamaterials. It is shown that in the low frequency limit multiple scattering allows us to define frequency-dependent effective acoustic parameters for arrays of both ...

Acoustic spin pumping in magnetoelectric bulk acoustic wave resonator
We present the generation and detection of spin currents by using magnetoelastic resonance excitation in a magnetoelectric composite high overtone bulk acoustic wave (BAW) resonator (HBAR) formed by a Al-ZnO-Al-GGG-YIG-Pt structure.

Hybrid integrated photonics using bulk acoustic resonators
Here, the authors demonstrate acousto-optic modulation of silicon nitride microring resonators using high-overtone bulk acoustic wave resonances, allowing modulation in the GHz range via acoustic waves.

Direct numerical simulation of wave propagation in saturated random granular packings using coupled LBM-DEM [PDF]
Poroelasticity theory predicts wave velocities in a saturated porous medium through a coupling between the bulk deformation of the solid skeleton and porous fluid flow.

Third-Harmonic and intermodulation distortion in bulk acoustic-wave resonators [PDF]
This article discusses on the measured third-order intermodulation (IMD3) products and third harmonics (H3) appearing in a set of six different solidly mounted resonators (SMR) and bulk acoustic-wave (BAW) resonators with different shapes and stack ...

Residual strain measurement based on longitudinal to shear wave velocity ratio with a dual-mode EMAT
In this paper, a new and noncontact method with measuring longitudinal to shear wave velocity ratio by a dual-mode electromagnetic acoustic transducer is proposed for residual strain measurement in a metal structure without knowing its thickness. Firstly,

Finite element error analysis of wave equations with dynamic boundary conditions: $L^2$ estimates [PDF]
$L^2$ norm error estimates of semi- and full discretisations, using bulk--surface finite elements and Runge--Kutta methods, of wave equations with dynamic boundary conditions are studied.

Correlation of BAW and SAW properties of langasite at elevated temperatures [PDF]
The full set of electromechanical data of langasite (La3Ga5SiO14) is determined in the temperature range from 20 to 900 °C using differently oriented bulk acoustic wave resonators.

Multiple wavemode scanning for near and far-side defect characterisation [PDF]
The combination of ultrasonic inspections using different wavemodes can give more information than is available with single mode inspection. In this work, the response of shear and Rayleigh waves to surface-breaking defects propagating on the near-side ...
