Modelling a wedge to steer the beam
In this paper, a numerical model for time-domain ultrasound plane wave propagation for a desired angle is presented. The propagating angle is a function of the distance and the time-delay between the individual elements, and the propagating sound speed.
In this model, the control parameter 'time' is used for steering the beam at the desired angle.
We present an application of the proposed beam steering model to simulate wave propagation in a moving medium.
