The adjacent composing channels are connected by space-varying air slits, thus realizing quantum-like adiabatic energy transfer. Equal-weight beam splitting with opposite phases from two different output ports is obtained in a broadband signal of 6 kHz-10.5 kHz. In addition, owing to the existence of distinct evolution paths, one-way beam division is exhibited when a certain loss is evenly exerted inside the system. Furthermore, one-to-m-port beam division can also be achieved by extending the composing channels, thus making it possible to construct an asymmetric acoustic beam splitter. The simulated results verify that the incident waves can be split into opposite directions unidirectionally, which may have potential applications in concealed information transmission and eavesdropping.<\/jats:p>","DOI":"10.3390\/e27090949","type":"journal-article","created":{"date-parts":[[2025,9,12]],"date-time":"2025-09-12T12:34:03Z","timestamp":1757680443000},"page":"949","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Realization of One-to-Two-Port Beam Division in a Five-Channel Acoustic System"],"prefix":"10.3390","volume":"27","author":[{"given":"Rui","family":"Wang","sequence":"first","affiliation":[{"name":"School of Navigation and Shipping, Shandong Jiaotong University, Weihai 264200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhicheng","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Research and Development, China Academy of Launch Vehicle Technology, Beijing 100076, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology, Weihai 264209, China"},{"name":"Weihai Shuangxin Metal Products Co., Ltd., Weihai 264299, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wencong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiabin","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Navigation and Shipping, Shandong Jiaotong University, Weihai 264200, China"},{"name":"School of Ocean Engineering, Harbin Institute of Technology, Weihai 264209, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haipeng","family":"Cui","sequence":"additional","affiliation":[{"name":"Qingdao JARI Industrial Control Technology Co., Ltd., Qingdao 266000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Navigation and Shipping, Shandong Jiaotong University, Weihai 264200, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Endaylalu, S.A., and Tien, W.-H.
