Acoustic waves : devices, imaging, and analog signal processing

TL;DR: Simulation results demonstrated that adequate focusing can be obtained with only four phase signals without large increases in the grating lobes or the dimensions of the focus, and the implementation of this method could have a large impact on ultrasound therapy and diagnostic devices.

TL;DR: The results of this study show that it is feasible to understand the acoustic transmission behavior of a flow phantom, based on a knowledge of the material properties, and to demonstrate the usefulness of doing so.

TL;DR: In this paper, the authors proposed the Electrically Stimulated Acoustic Wave (ESAW) method for observing resident space charge in dielectric insulators, which involves applying a fast and relatively small voltage pulse across a material containing space charge.

TL;DR: A new ultrasonic imaging technique, based on the spatio-temporal Green functions computation and cross-correlation, is presented, which extends the concept of matched field processing (MFP) used in ocean acoustics.
