Magneto-acoustic imaging by continuous-wave excitation

Medical & Biological Engineering & Computing, 2016
The electrical characteristics of tissue yield valuable information for early diagnosis of pathological changes. Magneto-acoustic imaging is a functional approach for imaging of electrical conductivity. This study proposes a continuous-wave magneto-acoustic imaging method.

Band Gap Regulation Mechanism and Rule of Locally Resonant Thermo-Magneto-Mechanical Phononic Crystal Double-Layer Nanobeam Based on Symmetric and Antisymmetric Vibration Modes

International Journal of Acoustics and Vibration
A locally resonant (LR) thermo-magneto-mechanical (TMM) phononic crystal (PC) double-layer nanobeam is presented, which is achieved by periodically attaching "vertical spring-precompressed horizontal spring-additional spring-mass" resonators onto the ...

On magneto-acoustic waves

Physics Letters, 1963
A solution is obtained for the induced magnetic field caused by the propagation of sound waves through an electrically conducting medium in a direction parallel to the original magnetic field. The equation of continuity is introduced into the coupled equations for the hydrodynamic flow and the electromagnetic field. (R.E.U.)

Magneto-Acoustic Waves in a Plasma

The Physics of Fluids, 1963
The propagation of plane magneto-acoustic waves in a highly conducting plasma is examined, and the results are applied to magneto-acoustic pulsations of a cylindrical configuration. (C.E.S.)

Experimental observations of magneto-acoustic fields

The Journal of the Acoustical Society of America, 1983
Experimental observations of electric fields induced in salt water by acoustic waves in a resonant cavity interacting with a strong constant magnetic field are described. The fields are found to behave linearly with the constant magnetic field strength as well as with the acoustic field strength as predicted theoretically.

On a Magneto-Acoustic Effect

Physical Review, 1941
In recent years considerable interest has developed'1 among chemists and physicists in the determination of the velocity of sound in liquids by means of high fre¬quency sound waves. These measurements are valuable for our knowledge of molecular properties.

Nonlinear magneto-acoustic waves in ferromagnets

Journal of Applied Physics, 1996
The nonlinear coherent interaction of a high-frequency acoustic wave pulse with a magnetically ordered medium is studied theoretically. We consider both microscopic and phenomenological theories of the formation of nonlinear magneto-acoustic waves in a ferromagnet.

Towards Magneto-Acoustic Oscillators

2017
Spin torque oscillators (STO) were developed in 2003 and since then great progress has been made in understanding their underlying physics, frequency of operation, frequency tuning range, and functionality. These nanoscale oscillators with their octave spanning frequency tuning range have been touted for many applications including neuromorphic ...

Magneto-acoustic oscillations in thallium

Physics Letters, 1962
Longitudinal sound wave transmission measurements were made nt frequencies up to 270 Mc/s in a single crystal of thallium. The resulting dimensions of the Fermi surface are compared with the predictions of the free electron model. The agreement is very good if a sirgle zone scheme is used, demonstrating the importance of spin-orbit effects on the band ...

Damping of nonlinear magneto-acoustic waves

Journal of Plasma Physics, 1978
Nonlinear magneto-acoustic waves in a turbulent plasma are simulated by collisional MHD equations. Damping of these waves due to electrical conductivity arising from micro-instabilities and collisional viscosity are analyzed. Numerical investigation of competing effects due to non-linearity and dissipation has been carried out.
