title = "Giant enhancement of the chiro-optic response of chiral plasmonic media using structured light",
abstract = "We propose an approach to achieve a great enhancement and broad spectral tunability of the chiro-optic response of plasmonic metasurfaces by exploiting their interaction with light of complex polarization, endowed with both spin (SAM) and orbital angular momentum (OAM). As a proof of principle, we employ full-wave computational analysis to investigate the response of a circularly polarized transverse Laguerre-Gaussian beam having a structured wavefront, incident on a chiral metasurface composed of a two-dimensional array of gold nanohelix meta-atoms. For the first time, our analysis reveals unprecedented amplification of circular dichroism, which is a manifestation of the total angular momentum of incident light being enantio-selectively transferred to the chiral medium.",
