Chiral sensing with achiral isotropic metasurfaces
Sotiris Droulias
Metasurfaces, the two-dimensional analogues of metamaterials, are ideal platforms for sensing molecular chirality at the nanoscale, e.g. of inclusions of natural optically active m…
Scattering properties of PT-symmetric chiral metamaterials
Ioannis Katsantonis, Sotiris Droulias, Costas M. Soukoulis +2
The combination of gain and loss in optical systems that respect parity-time (PT)-symmetry has pointed recently to a variety of novel optical phenomena and possibilities. Many of t…
PT-symmetric chiral metamaterials: Asymmetric effects and PT-phase control
Ioannis Katsantonis, Sotiris Droulias, Costas M. Soukoulis +2
We investigate the influence of chirality on the PT-symmetric and PT-broken phase of PT-symmetric chiral systems. Starting from the point that transverse magnetic (TM) and transver…
Absolute chiral sensing in dielectric metasurfaces with signal reversals
Sotiris Droulias, Lykourgos Bougas
Sensing molecular chirality at the nanoscale has been a long-standing challenge due to the inherently weak nature of chiroptical signals, and nanophotonic approaches have proven fr…
