Ultrasound Field Simulation
Ultrasim is an interactive, menu-oriented simulator for finding the sound field from transducers, primarily for medical ultrasound. Ultrasim can handle 1D, 1.5D and 2D linear and phased arrays, and flat and curved arrays with many different footprints such as rectangular and elliptical. It also handles annular arrays, axicons and Bessel transducers. Each simulation consists of a numerical integration of the contribution from all sub-elements of a transducer. The transducer excitation can be either continuous wave (CW) or a broad-band pulsed wave (PW). The simulator is implemented as a toolbox in MATLAB.

TASI Technical Software
currently has software tools for the analysis of small signal piezoelectric properties, and large signal characterisation of piezoeoelectric, electrostrictive, ferroelectric, and antiferroelectric materials. Each software package is modular where extended features are supported through plug-in software modules. Each package also includes an optional data acquisition module allowing the collection of raw data directly from instrumentation.
