Abstract:
In this paper, we propose a new numerical method for ultrasonic pulse detection of an acoustics microwaves
signal during the propagation of acoustics microwaves generated by piezoelectric substrate LiNbO3
Cut Y-X in ultrasonic transducer. We have used the classifications by support vector machines (SVM), the
originality of this method is it provides the accurate values and help us to identify undetectable waves that
we cannot identify with the classical methods; in which we classify all the values of the real part and the
imaginary part of the coefficient attenuation with the acoustic velocity in order to build a model from which
we note the Ultrasonic Pulse or microwaves acoustics ( bulk waves ). By which we obtain accurate values for
each of the coefficient attenuation and acoustic velocity. This study will be very interesting in modeling and
realization of acoustics microwaves devices (ultrasound) based on the propagation of acoustics microwaves.
