The basics of nonlinear acoustics and its application to medical ultrasound imaging are introduced. First, a little historical introduction is given, and next, the coefficient of nonlinearity is introduced, together with a variety of equations, which step by step develop from simple to more sophisticated models.

Physics Today, 1955
AN INTELLECTUALLY VITAL and stimulating field, acoustics is rich in unsolved and intriguing research problems. Its areas of interest are pertinent to the activities of many traditional university departments: mathematics, physics, electrical engineering, mechanical engineering, land and naval architecture, behavioral sciences and even biology, medicine

International Journal of Bifurcation and Chaos, 1991
The history of chaos pertaining to acoustics is briefly reviewed from the first period-doubling experiments reported by Faraday (vibrated liquid layer) and Melde (string oscillations) to today's investigations on chaos in thermoacoustics, musical instruments, the hearing process, and ultrasonics.

Twisted Acoustics: Metasurface‐Enabled Multiplexing and Demultiplexing
Advances in Materials, 2017Metasurfaces are used to enable acoustic orbital angular momentum (a‐OAM)‐based multiplexing in real‐time, postprocess‐free, and sensor‐scanning‐free fashions to improve the bandwidth of acoustic communication, with intrinsic compatibility and ...

Theoretical and Computational Fluid Dynamics, 1998
We discuss two types of acoustic streaming, namely the ``quartz wind'' and Rayleigh streaming. Both are associated with flows that are dominated by their fluctuating components, and owe their origin to the action of Reynolds stresses. In the former, these stresses arise within the main body of the fluid when an ultrasonic beam propagates into it; in ...

The Journal of the Acoustical Society of America, 1991
A stable force potential well was generated by two collimated focused ultrasonic (3.5 MHz) beams propagating along opposite directions. Latex particles (270-μm diameter) and clusters of frog eggs were trapped in the potential well. The trapped object can be moved axially or laterally by moving one of the PZT focusing transducers that generate the ...

Eight nerve tumors account for about 8 to 10% of all intracranial tumors, and for about 71 to 75% of all cerebello-pontine angle tumors. They occur particularly in the middle decades of life and are twice as frequent in females as in males. They originate from the distal neurolemmal portion of the nerve, in most instances, from the vestibular division,
