To calculate the transmission coefficient of ultrasonic waves through a multi-layered medium, a new approach is proposed by expanding it into Debye’s series. Using this formalism, the transmission coefficient can be put in the form of resonance ter

The measurement of nonlinear parameter of the propagating medium using finite amplitude techniques is based on the detection of the second harmonic generated nonlinearly in the investigated medium. This method requires an analytical expression for th

A procedure for measurement of the nonlinear B/A parameter using a simple comparative method is presented. A theoretical model of the measurement system is proposed. The sensitivity function of the measurement system is carried out and related to the

During its propagation in a given medium, the ultrasonic wave is disturbed by several phenomena that affect the waveform in both time and frequency domains. Among these phenomena, the most important are absorption, nonlinearity, and diffraction. The

Transducer is the most important element in an ultrasonic device because it governs the conversion of electrical energy to acoustical one and vice versa. Therefore it's very important to predict its behaviour and to determine its optimal domain of fu

In this paper, we propose a new method for simulating three-dimensional (3D) ultrasonic wave propagation using P-Spice like simulator. We use a one-dimensional transmission line model to implement the diffraction losses. In order to simulate the beam
