Magneto-acoustic investigation on steel samples
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Experiments have been carried out using yoke for energizing alternating magnetic field in the steel samples. We used acoustic emission sensors and ultrasound microphone for recording acoustic signal born in the steel material. Results of experiments clearly show the presence of Acoustic Barkhausen noise.

The dissipation of magneto-acoustic waves
Computers & Mathematics with Applications, 1994 The propagation of magneto-acoustic waves in a thermally conducting isothermal atmosphere, in the case of dominant magnetic field, is studied. It is shown that the atmosphere may be divided into two distinct regions: the lower region where the motion is approximately adiabatic, and the upper region where the solution decays with the altitude to a ...

Mathematical models and reconstruction methods in magneto-acoustic imaging [PDF]
European Journal of Applied Mathematics, 2009 In this paper, we provide the mathematical basis for three different magneto-acoustic imaging approaches (vibration potential tomography, magneto-acoustic tomography with magnetic induction and magneto-acoustic current imaging) and propose new algorithms for solving the inverse problem for each of them.

Synthetic phonons enable nonreciprocal coupling to arbitrary resonator networks [PDF]
Science Advances, 2017 Wavelike spatiotemporal modulation of discrete coupling elements creates synthetic phonons that enable nonreciprocal coupling. Inducing nonreciprocal wave propagation is a fundamental challenge across a wide range of physical systems in electromagnetics,
