However, achieving simultaneous stable levitation and dexterous pose control of irregularly shaped objects remains a challenge. This paper introduces a cluster-optimization method for generating a radially asymmetric enhanced standing-wave field (RA-ESWF) using opposed ultrasonic arrays. The method dynamically derives feature phase patterns from a field-phase mapping dataset, avoiding predefined templates, and integrates them with parametric optimization to decouple orientation-locking and positional-focusing functions. Experiments demonstrate that the RA-ESWF effectively balances strong levitation force with precise orientation control. It enables pose manipulation of objects with diverse shapes and sizes (including near-spherical and rod-like samples) while maintaining high angular stability (standard deviation: 0.614\u00b0) and positional precision (0.048\u2009mm in X, 0.069\u2009mm in Y). The proposed method extends the functionality of conventional opposed-array levitators and offers a robust, optimization-driven framework for advanced acoustic trapping and manipulation in applications such as micro-reactors, biological sample handling, and non-contact assembly.<\/jats:p>","DOI":"10.1121\/10.0044586","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T11:54:22Z","timestamp":1786103662000},"page":"1172-1181","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A cluster-optimization method for enhanced standing-wave acoustic fields: Stable levitation and pose manipulation of irregularly shaped objects"],"prefix":"10.1121","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3367-9182","authenticated-orcid":false,"given":"Liangxu","family":"Jiang","sequence":"first","affiliation":[{"name":"College of Communication Engineering, Jilin University , Changchun 130022,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4621-762X","authenticated-orcid":false,"given":"Zongqi","family":"Bai","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Jilin University , Changchun 130022,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-3368-9460","authenticated-orcid":false,"given":"Enshun","family":"Ren","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Jilin University , Changchun 130022,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1888-5283","authenticated-orcid":false,"given":"Junfan","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Jilin University , Changchun 130022,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1628-1033","authenticated-orcid":false,"given":"Xinbo","family":"Li","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Jilin University , Changchun 130022,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"2026080707541832000_c1","doi-asserted-by":"publisher","first-page":"480","DOI":"10.1038\/s42254-020-0215-3","article-title":"Comparing acoustic and optical forces for biomedical research","volume":"2","year":"2020","journal-title":"Nat.
