A novel modulation approach based on nonlinear acoustic signals for underwater communications.
(European Acoustics Association, 2023)Nonlinear acoustics is the catalyst of a new generation of applications that are exploited in different fields. The parametric nonlinear effect, i.e. the appearance of extra harmonics in the spectrum besides the fundamental ... -
Characterization of a Piezoelectric Acoustic Sensor Fabricated for Low-Frequency Applications: A Comparative Study of Three Methods
(MDPI, 2023-03-02)Piezoelectric transducers are widely used for generating acoustic energy, and choosing the right radiating element is crucial for efficient energy conversion. In recent decades, numerous studies have been conducted to ... -
Proof of Concept of the Use of the Parametric Effect in Two Media with Application to Underwater Acoustic Communications.
(MDPI, 2023-08-15)Nonlinear acoustics offers a new range of acoustic applications that are currently being exploited. The parametric nonlinear effect—the occurrence of low frequencies with modulated high-frequency emission—is of particular ... -
Técnicas de modulación para las comunicaciones acústicas no lineales.
(2018)Non-linear acoustics offers a new era in acoustic applications that are currently being exploited in different fields. The non-linear parametric effect, i.e, the appearance of extra harmonics in the spectrum besides the ...
