  1. 55. Reciprocal Asymmetric Transmission: A Way Passed From Plane Waves To Metaholograms
    Dr Andriy Serebryannikov (ISQI, Faculty of Physics, Adam Mickiewicz University)
    11/7/24, 3:15 PM
    Invited Talk

    Reciprocal Asymmetric Transmission (RAT) has attracted attention of the metamaterial, photonic crystal, and artificial chirality communities since 2000’s. Initially, RAT has been understood as the difference in transmission when the structure with broken spatial inversion symmetry is illuminated by the same linearly or circularly polarized wave in forward and backward (i.e., opposite)...

  2. 69. Manipulating over reflection, polarization and collection of light with metasurfaces
    Oleh Yermakov (Leibniz Institute of Photonic Technology)
    11/7/24, 3:45 PM
    Invited Talk

    Two-dimensional (2D) materials offer unique opportunities for photodetection, light emission, energy harvesting, and enhanced light-matter interactions. Even more interest brings the artificially engineered 2D micro- and nanostructures with on-demand properties paving the way towards a plethora of specific applications and devices including lensing, holography, imaging, polarimetry,...

    Oral

    Hyperbolic metasurfaces are known for their dispersion and polarization properties, such as negative refraction, hyperlensing, enhanced spontaneous emission, etc [1]. The surface waves localized at hyperbolic metasurfaces are called hyperbolic plasmon-polaritons and exhibit a lot of potential applications for planar technologies [2].
    In this work, we analyze the dependencies of the spectral...

  4. 104. Inverse design of antireflection silicon-on-silicon coatings
    Anton Ovcharenko (V. N. Karazin Kharkiv National University)
    11/7/24, 4:30 PM
    Oral

    Designer gratings, also known as metagratings, can be tuned to preform various kinds of tasks, such as amplify deflection in a particular diffraction order, increase or decrease transmission and reflection [1]. A typical task for various kinds of coatings is to reduce reflection from a surface. Inspired by this, we set out to design a single-layer silicon metagrating as an antireflection cover...

  5. 16. Enhanced chiral sensing with plasmonic nanostructures
    Oleh Demianyk (V.N. Karazin Kharkiv National University, 4 Svobody Square, Kharkiv 61022, Ukraine)

    Oral

    Chirality is used to describe an object that is not superposable on its mirror image. Despite having the same chemical structure, most chiral molecules show significant differences in biological activity, being the poison or the drug depending on the handedness. The main difficulty during the measurement of chiral substances is the need to detect extremely weak chiroptical signals from a small...
