Here, we propose an indirect magneto\u2010optical (MO) coupling mechanism that originates from the spatially asymmetric near\u2010field distribution of resonant modes, rather than from the direct coupling between the incident field and the MO tensor. Guided by this principle, we design a quasi\u2010two\u2010dimensional MO grating that strategically coordinates resonances along two orthogonal directions. Specifically, modes perpendicular to the grating ridges establish a wide\u2010angle broadband near\u2010zero reflection background to satisfy the rigorous mathematical condition for maximum TMOKE, whereas the orthogonal high\u2010Q resonances are responsible for inducing maximal near\u2010field asymmetry. This allows us to push the s\u2010polarized TMOKE to approach its theoretical limit (\u223c2)\u2014a performance leap of over an order of magnitude compared to previous reports. The proposed structure exhibits exceptional robustness against material losses and fabrication tolerances, alongside a broad angular tolerance (up to 40\u00b0), offering a practical blueprint for high\u2010performance nonreciprocal photonic devices.<\/jats:p>","DOI":"10.1002\/nap2.70139","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T05:39:10Z","timestamp":1778823550000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Giant
