Yahiaoui, Riad; Manjappa, Manukumara; Srivastava, Yogesh Kumar; Singh, Ranjan, 2021, "Replication Data for: Active control and switching of broadband electromagnetically induced transparency in symmetric metadevices", https://doi.org/10.21979/N9/LMVFSX, DR-NTU (Data), V1
Electromagnetically induced transparency (EIT) arises from coupling between the bright and dark mode resonances that typically involve subwavelength structures with broken symmetry, which results in an extremely sharp transparency band. Here, we demonstrate a tunable broadband EI...
