Our study focuses on the impact of the incident angle on the GHS, considering the coupling between longitudinal and transverse modes. For acoustic vibrations, our findings reveal that the GHS can reach magnitudes up to seven times larger than the thickness of the thin film and up to 20 times larger than the incident wavelength. Besides, it is shown that this significant amplification of the GHS highlights the strong influence of the incident angle and the frequency of the modes involved. In the case of optical vibrations, we observe even more pronounced GHS values, exceeding 30 times the incident wavelength. This demonstrates the potential of GHS in acoustical systems, which opens up possibilities for applications in the design of acoustic devices. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.6 2024 PHYSICS, CONDENSED MATTER 43 / 80 = 0.538 2024 Q3 T2 0.624 2024 Materials Science (miscellaneous) 2024 Q2 Condensed Matter Physics 2024 Q2 4.6 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lazcano, Zorayda Arriaga, Jesús Pérez-Álvarez, R León-Pérez, Fernando de Universidad de Zaragoza (orcid)0000-0003-0381-3448 2003 395 Universidad de Zaragoza Dpto.
