The analytical formulation combines the transverse equivalent network and the transverse resonance equation to predict leaky-mode dispersion parameters, including the phase constant and leakage rate. Compared with previously reported metamaterial-based ALWAs, which rely on complex resonant unit cells and exhibit limited scanning performance, the proposed structure provides a simpler alternative while maintaining effective beam-steering capability. The proposed approach bridges the gap between theoretical modeling and practical implementation, establishing a robust framework for the design and optimization of compact and cost-effective ALWAs suitable for acoustic sensing, communication, and localization applications.<\/jats:p>","DOI":"10.1121\/10.0046796","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T16:59:05Z","timestamp":1791910745000},"page":"2988-3002","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A quasi-uniform acoustic leaky-wave antenna: Analysis, design and experimental validation"],"prefix":"10.1121","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7227-6001","authenticated-orcid":false,"given":"Jens","family":"Forss\u00e9n","sequence":"first","affiliation":[{"name":"Division of Applied Acoustics, Department of Architecture and Civil Engineering, Chalmers University of Technology 1 , SE-412 96 Gothenburg,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo-Antonio","family":"Mart\u00ednez-Vicente","sequence":"additional","affiliation":[{"name":"Department of Communication and Information Technologies, Technical University of Cartagena 2 , 30202 Cartagena,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Astrid","family":"Algaba-Braz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Communication and Information Technologies, Technical University of Cartagena 2 , 30202 Cartagena,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Polidano","sequence":"additional","affiliation":[{"name":"Division of Applied Acoustics, Department of Architecture and Civil Engineering, Chalmers University of Technology 1 , SE-412 96 Gothenburg,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9-Luis","family":"G\u00f3mez-Tornero","sequence":"additional","affiliation":[{"name":"Department of Communication and Information Technologies, Technical University of Cartagena 2 , 30202 Cartagena,","place":["Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,10,13]]},"reference":[{"key":"2026101312590429900_c1","unstructured":"W.
