Here, we study a metasurface composed of tilted achiral meta-atoms with no spatial variation of the unit cell that derives appreciable optical chirality solely from the asymmetric interactions between meta-atoms. The interactions between meta-atoms are considered to stem from the Lorentz force arising from the Larmor radiation of adjacent plasmonic resonators because their inclusion in a simple model accurately predicts the bonding\/anti- bonding modes that are measured experimentally. We also experimentally observe the emergence of multiple polarization eigenmodes, among other polarization-dependent responses, which cannot be modeled with the conventional formalism of transmission matrices. Our results are vital to the precise characterization and design of metasurfaces.<\/jats:p>","DOI":"10.1038\/srep40718","type":"journal-article","created":{"date-parts":[[2017,2,8]],"date-time":"2017-02-08T11:43:44Z","timestamp":1486554224000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Meta-Optical Chirality and Emergent Eigen-polarization Modes via Plasmon Interactions"],"prefix":"10.1038","volume":"7","author":[{"given":"Matthew","family":"Moocarme","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas V.","family":"Proscia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luat T.","family":"Vuong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,2,8]]},"reference":[{"key":"BFsrep40718_CR1","doi-asserted-by":"publisher","first-page":"205428","DOI":"10.1103\/PhysRevB.84.205428","volume":"84","author":"Y Zhao","year":"2011","unstructured":"Zhao, Y. & Alu, A.
