摘要

Bound states in the continuum are realized in many optical systems as"dark states", and their presence can be detected in the regime of leaky modes via resonances in far-fields. Here the authors reveal previously unseen structure of bound states in the continuum by exploring strong near-field localization in dielectric metasurfaces.
