Here, we report an all\u2010dielectric asymmetric gammadion metasurface that exhibits pronounced circular dichroism (CD) in the visible spectral range. By breaking the in\u2010plane mirror symmetry of the unit cell, strong polarization\u2010selective resonances are induced under circularly polarized illumination. Numerical simulations and experiments reveal two distinct CD resonances near 652 and 735\u00a0nm with maximum absolute CD values exceeding 50% and 40%, respectively. Electromagnetic multipole decomposition shows that the strong CD at 652\u00a0nm originates from selective excitation of high\u2010order electric and magnetic modes under right\u2010handed circularly polarized illumination leading to a large imbalance in multipolar scattering and strongly localized chiral near fields. In contrast, the weaker CD at 735\u00a0nm arises from a more symmetric and reduced multipolar excitation landscape. Angle\u2010resolved analyses further demonstrate that the quadrupole\u2010dominated resonance maintains robust CD under oblique incidence, whereas the simpler multipolar excitation at 735\u00a0nm yields a more angle\u2010insensitive but moderate CD response. These results establish a physical link between structural asymmetry, multipolar excitation, near\u2010field optical chirality, and angle\u2010resolved chiroptical behavior, providing practical design guidelines for low\u2010loss dielectric metasurfaces with robust chiroptical responses.<\/jats:p>","DOI":"10.1002\/nap2.70153","type":"journal-article","created":{"date-parts":[[2026,5,28]],"date-time":"2026-05-28T07:22:22Z","timestamp":1779952942000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High\u2010Order Multipolar Excitations Governing Circular Dichroism in an All\u2010Dielectric Chiral Metasurface"],"prefix":"10.1002","volume":"15","author":[{"given":"Chien\u2010Feng","family":"Chien","sequence":"first","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0109-6297","authenticated-orcid":false,"given":"Hsiu\u2010Ping","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu\u2010Tsung","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu\u2010Fei","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5781-9696","authenticated-orcid":false,"given":"Pin Chieh","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Photonics National Cheng Kung University  Tainan Taiwan"},{"name":"Center for Quantum Frontiers of Research &amp;
