This paper presents an ultrasonic transducer modeling with VHDL-AMS standard (Very High
speed integrated circuits Hardware Description Language–Analog and Mixed Signal) …

In this paper, FD formulations in cylindrical coordinates are used to model the field radiated,
by a circular source, in fluid and solid media. The stability of the used schemes is controlled …

A model is presented for the analysis of thickness-mode piezoelectric transmitters under
practical operating conditions. The systems feedback approach is employed to clearly …

Computer simulation has been used widely in medical ultrasonic transducer designs. One
could now construct and test an transducer entirely ion a virtual basis. Such a virtual design …

In ultrasonic physiotherapy, the therapeutic effect is produced in the first 5 cm, into the
Fresnel zone. Models are focused principally in the Fraunhofer zone which is too far from the …

A new model of ultra-acoustic transducer is described, which allows the time response to a
voltage pulse to be evaluated directly. The analysis performed refers to the emission of …

A transducer, as applied to ultrasonic testing, is the means by which electrical energy is
converted into acoustic energy and back again. The device, adapted for UT, has been called …

Ultrasonic converters, horns, and nondestructive inspection transducers can be accurately
designed using the one dimensional (1D) wave equation. The segments that form the …

A general three-dimensional (3D) theoretical model for simulating the behaviour of
micromachined electrostatic ultrasonic transducers has been developed. The model takes …

The design, properties and optimization of an ul-trasonic actuator are presented. Numerical
modeling has been carried out and simulations with the FEM Ansys software have been …
