We show that this approach produces two distinct extreme sublattices within a supercell, leading to the emergence of staggered band structures associated with flatband formation. In the full-wave simulation with a square lattice, we clearly find a flatband emerging within the predicted spectral range, which has a mode profile localized at the predefined region. Besides, such a flatband resonance is found to exist persistently in a finite-size single-cell slab, while the supercell size is inherently scalable. Particularly, by increasing the supercell size from 7\n                    <jats:italic>a<\/jats:italic>\n                    to 9\n                    <jats:italic>a<\/jats:italic>\n                    , the quality factor of the moir\u00e9 resonance rises dramatically from \u223c0.67\u00d710\n                    <jats:sup>4<\/jats:sup>\n                    to \u223c3.1\u00d710\n                    <jats:sup>4<\/jats:sup>\n                    . Furthermore, as the far-field radiation profile is practically important, we introduce a new degree of freedom, i.e., the topological alignments of anisotropic scatterers, and demonstrate its effectiveness in shaping the far-field patterns. This work thus offers an attractive route toward high-performance moir\u00e9 resonators, which is relevant to applications such as the development of micro lasers and nonlinear optical devices.\n                  <\/jats:p>","DOI":"10.1364\/ol.608427","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T13:00:08Z","timestamp":1787230808000},"page":"5301","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tailoring monolayer moir\u00e9-flatband superlattices through long-range lattice-site perturbations"],"prefix":"10.1364","volume":"51","author":[{"given":"Wenjing","family":"Li","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuge","family":"Qiu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinying","family":"Peng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangqi","family":"Huang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuhao","family":"Ji","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1842-4608","authenticated-orcid":true,"given":"Liwei","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingfang","family":"Yi","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peilong","family":"Hong","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0127ytz78","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Nankai University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"ol-51-19-5301-R1","doi-asserted-by":"publisher","first-page":"201","DOI":"10.1038\/s41578-021-00284-1","type":"journal-article","volume":"6","author":"Andrei","year":"2021","journal-title":"Nat.
