We propose Brillouin zone folding (BZF) based on lattice perturbations to achieve multiple ultrahigh-Q toroidal dipole (TD) resonances, enabling polarization- and incident angle-independent enhancement of the magneto-optical Kerr effect at multiple wavelengths. The metasurface achieves perfect 180\u00b0 Kerr rotation near TD resonances, with the polarization direction designable at any angle. The enhancement arises from prolonged light-magneto-optical medium interaction, which strengthens electric field confinement and magneto-optic coupling. The BZF-TD mode exhibits a tunable quality factor, offering an approach for multi-band nonlinear enhancement. We also demonstrate a refractive index sensor based on enhanced Kerr rotation with a sensitivity of 224\u2005nm\/RIU.<\/jats:p>","DOI":"10.1364\/oe.593054","type":"journal-article","created":{"date-parts":[[2026,5,4]],"date-time":"2026-05-04T04:00:08Z","timestamp":1777867208000},"page":"19986","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Wide-angle and polarization-insensitive magneto-optical Kerr effect enhancement empowered by Brillouin zone folding driven toroidal dipole resonances"],"prefix":"10.1364","volume":"34","author":[{"given":"Zhichun","family":"Fan","sequence":"first","affiliation":[{"name":"Jimei University"},{"name":"Fujian Provincial Key Laboratory of Oceanic Information Perception and Intelligent Processing"},{"name":"Fujian Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Wang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03panb555","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hengwei","family":"Shen","sequence":"additional","affiliation":[{"name":"Jimei University"},{"name":"Fujian Provincial Key Laboratory of Oceanic Information Perception and Intelligent Processing"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tongyu","family":"Yao","sequence":"additional","affiliation":[{"name":"Jimei University"},{"name":"Fujian Provincial Key Laboratory of Oceanic Information Perception and Intelligent Processing"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"key":"oe-34-11-19986-R1","doi-asserted-by":"publisher","first-page":"076401","DOI":"10.1088\/0034-4885\/79\/7\/076401","type":"journal-article","volume":"79","author":"Chen","year":"2016","journal-title":"Rep.
