This article reports some preliminary results in the development of a finite element simulator
for ultrasonic fields using the numerical programming library Diffpack. In our present work …

Over the last few decades medical ultrasound has become an established diagnostic and
therapeutic tool since it produces detailed and high resolution images of tissues in human …

The pressure field emitted from multi-element medical ultrasound transducers can be
simulated with Field II in the linear regime. By expanding this program's application to the …

By using a small number of Gaussian basis functions, one can synthesize the wave fields
radiated from planar and focused piston transducers in the form of a superposition of …

An algorithm is developed for fully nonlinear three-dimensional (3D) simulation of a
difference-frequency acoustic beam resulting from the interaction of two high-intensity pump …

On the basis of recently developed Fourier continuation (FC) methods and associated
efficient parallelization techniques, this text introduces numerical algorithms that, due to very …

The free space solution to the wave equation in spherical coordinates is well known as a
separable product of functions. Re-examination of these functions, particularly the sums of …

A multi-Gaussian beam model is a computationally very efficient approach for modeling the
sound beam generated by an ultrasonic piston transducer radiating into complex geometries …

THE problem of underwater blast-wave focusing over truncated ellipsoidal re ectors is
considered. Namely, a blast wave is initiated, which will be propagating into a quiet water …

A technique useful for performing derating at acoustic powers where significant harmonic
generation occurs is illustrated and validated with experimental measurements. The …
