However, the inherent propagation divergence and performance degradation under angular deviation severely restrict their practical applications. This paper proposes a transmissive focusing metasurface that maintains stable OAM vortex wave generation under angular deviation. By employing a quadratic phase distribution, the proposed design fundamentally eliminates the axial focal shift caused by oblique incidence and maintains stable focusing performance. A three-metal-layer transmissive unit is developed to achieve high cross-polarization transmittance and full 2\u03c0 phase coverage. By combining the quadratic focusing phase and OAM spiral phase, the metasurface enables stable generation of high-purity focused OAM beams under angular deviation. A prototype is fabricated and experimentally characterized, which verifies the theoretical predictions under the designed incident angle and angular deviation scenarios. Furthermore, a wireless communication system based on the Universal Software Radio Peripheral (USRP) is constructed in this work, which achieves reliable transmission and demodulation verification of 16-quadrature amplitude modulation (16-QAM) signals. The proposed metasurface provides a feasible solution for short-to-medium distance robust transmission of OAM waves and shows good application potential in practical wireless communication systems.<\/jats:p>","DOI":"10.1021\/acsomega.6c05118","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T07:01:45Z","timestamp":1789455705000},"page":"57222-57230","source":"Crossref","is-referenced-by-count":0,"title":["Wide-Angle Stable\nTransmissive Focusing Metasurfaces\nfor OAM Vortex Waves in Wireless Communications"],"prefix":"10.1021","volume":"11","author":[{"given":"Yi","family":"Zhong","sequence":"first","affiliation":[{"name":"Xi\u2019an University of Science and Technology , , ,","place":["Xi\u2019an, China, 710054"]},{"name":"Universities of Shaanxi Province , , ,","place":["Xi\u2019an, China, 710054"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luyao","family":"Wang","sequence":"additional","affiliation":[{"name":"Xi\u2019an University of Science and Technology , , ,","place":["Xi\u2019an, China, 710054"]},{"name":"Universities of Shaanxi Province , , ,","place":["Xi\u2019an, China, 710054"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifei","family":"Wang","sequence":"additional","affiliation":[{"name":"Xi\u2019an University of Science and Technology , , ,","place":["Xi\u2019an, China, 710054"]},{"name":"Universities of Shaanxi Province , , ,","place":["Xi\u2019an, China, 710054"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayun","family":"Yu","sequence":"additional","affiliation":[{"name":"Xi\u2019an University of Science and Technology , , ,","place":["Xi\u2019an, China, 710054"]},{"name":"Universities of Shaanxi Province , , ,","place":["Xi\u2019an, China, 710054"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7685-2678","authenticated-orcid":true,"given":"Xiaojun","family":"Huang","sequence":"additional","affiliation":[{"name":"Xi\u2019an University of Science and Technology , , ,","place":["Xi\u2019an, China, 710054"]},{"name":"Universities of Shaanxi Province , , ,","place":["Xi\u2019an, China, 710054"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"2026092911104098600_cit1","doi-asserted-by":"publisher","first-page":"18","DOI":"10.1038\/s41377-025-02107-2","article-title":"OAM multiplication\noperator enabled holographic multiplexing","volume":"15","author":"Shen","year":"2026","journal-title":"Light:\nSci.
