Although recently proposed metasurfaces have addressed this challenge, meta\u2010couplers realized so far exhibit inevitable frequency dispersions, restricting their practical applications. Here, we propose a scheme to design on\u2010chip achromatic metasurfaces that can decouple SWs within a continuous frequency band to far\u2010field beams traveling along the same direction. Our metadevices, composed of composite meta\u2010atoms exhibiting pre\u2010designed reflection phases with tailored frequency dispersion dictated by both resonant and Pancharatnam\u2013Berry phase mechanisms, can compensate the desired frequency\u2010dependent wavevectors for SWs at different frequencies, thereby generating unidirectional far\u2010field beams. As a proof of concept, we design and fabricate two on\u2010chip achromatic metasurfaces working in the microwave regime and experimentally demonstrate that they can achieve in\u2010plane and out\u2010of\u2010plane unidirectional far\u2010field decoupling of SWs, exhibiting relative frequency bandwidths of 22.22% and 37.04%, respectively. Both microwave experiments and full\u2010wave simulations successfully confirm our theoretical predictions. These findings pave the way for on\u2010chip photonic manipulations and related applications, including wireless communication, signal processing, high\u2010sensitivity sensing, and so on.<\/jats:p>","DOI":"10.1002\/nap2.70064","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T14:06:13Z","timestamp":1775829973000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unidirectional
