Kiefer","Georg Watzl","Katharina Burgholzer","Martin Ryzy","Clemens Grünsteidl"],"abstract":"Electroelastic waves in piezoelectric media are widely used in sensing and filtering applications. Despite extensive research, computing the guided wave dispersion remains challenging. This paper presents semi-analytical approaches based on spectral methods to efficiently and reliably compute dispersion curves. We systematically assess the impact of electrical boundary conditions on a 128{\\deg} Y-cut LiNbO3 wafer, examining open-open, open-shorted and shorted-shorted surfaces configurations. Multi-modal dispersion maps obtained from laser-ultrasonic experiments for each boundary condition exhibit excellent agreement with the computational predictions. A straightforward implementation of the spectral collocation method is made available as \"GEW piezo plate\" (https://doi.org/10.5281/zenodo.14205789), while the spectral element method will be integrated to \"GEWtool\" (http://doi.org/10.5281/zenodo.10114243). Therewith, we aim to make advanced semi-analytical techniques more accessible to physicists and engineers relying on dispersion analysis.","url_abs":"https://arxiv.org/abs/2412.07389v1","url_pdf":"https://arxiv.org/pdf/2412.07389v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"electroelastic-guided-wave-dispersion-in","repo_url":"https://github.com/dakiefer/GEW_piezo_plate","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null},{"paper_slug":"electroelastic-guided-wave-dispersion-in","repo_url":"https://github.com/dakiefer/gewtool","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
