The scattering of ultrasonic waves by polycrystals

Physica Status Solidi (a), 1981
The attenuation coefficients of longitudinal and transverse waves are calculated for polycrystals of triclinic and higher symmetries over the entire frequency range. The calculation is made in the Bourret approximation by the methods of renormalization of the wave equation and re-expansion taking account of multiple scattering, with exponential ...

Continuous wave ultrasonic tomography

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2001
As an object rotates with respect to a stationary ultrasonic beam, the scattering centers within the object return echoes that are Doppler-shifted in frequency by amounts depending on the velocities of the individual scatterers. The scattering centers that lie on a line of constant cross-range all have the same effective velocity in the direction ...

A Study of Emulsification with Ultrasonic Waves I*

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
An attempt has been made to study and evaluate some of the factors involved in emulsification with ultrasonic energy. The stability of the emulsifying agent to ultrasonic waves is a factor in its choice in emulsification. Two exposure chambers were found to be superior; one a cellulose acetate chamber and the other a Pyrex test tube fitted with a brass

Ultrasonic Waves and Electrochemistry. III. An Electrokinetic Effect Produced by Ultrasonic Waves

The Journal of the Acoustical Society of America, 1953
If a wire covered with a fiber or a porous coating is submerged in a dilute electrolytic solution and irradiated with ultrasonic waves, an alternating potential of the same frequency is produced on the wire relative to the bulk of the surrounding solution.
