However, critical aspects at fundamental and experimental levels have yet to be disclosed to optimize their operational conditions. Identifying the processes and mechanisms by which different types of AWs induce de‐icing are some of these issues. Herein, using model LiNbO3 systems and two types of interdigitated transducers, the e‐icing and anti‐icing efficiencies and mechanisms driven by Rayleigh surface acoustic waves (R‐SAW) and Lamb waves with 120 and 510 μm wavelengths, respectively, are analyzed. Through the experimental analysis of de‐icing and active anti‐icing processes and the finite element simulation of the AW generation, propagation, and interaction with small ice aggregates, it is disclosed that Lamb waves are more favorable than R‐SAWs to induce de‐icing and/or prevent the freezing of small ice droplets. Prospects for applications of this study are supported by proof of concept experiments, including de‐icing in an icing wind tunnel, demonstrating that Lamb waves can efficiently remove ice layers covering large LN substrates. Results indicate that the de‐icing mechanism may differ for Lamb waves or R‐SAWs and that the wavelength must be considered as an important parameter for controlling the efficiency. info:eu-repo/grantAgreement/ES/AEI/PID2022-143120OB-I00 info:eu-repo/grantAgreement/EUR/AEI/TED2021-130916B-I0 info:eu-repo/grantAgreement/EC/H2020/899352/EU/Sustainable Smart De-Icing by Surface Engineering of Acoustic Waves/SOUNDofICE This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 899352-SOUNDofICE info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.3 2024 MATERIALS SCIENCE, MULTIDISCIPLINARY 227 / 461 = 0.492 2024 Q2 T2 0.76 2024 Condensed Matter Physics 2024 Q1 Materials Science (miscellaneous) 2024 Q2 5.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion del Moral, Jaime Jacob, Stefan Montes, Laura Gil-Rostra, Jorge Frechilla, Alejandro Universidad de Zaragoza Karimzadeh, Atefeh Rico, Victor J.
