  • Invited Article: Direct phase mapping of broadband Laguerre-Gaussian metasurfaces 

    Faßbender, Alexander; Babocký, Jiří; Dvořák, Petr; Křápek, Vlastimil; van der Linden, Stefan (AIP Publishing, 2018-11-01)
    We report on the fabrication of metasurface phase plates consisting of gold nanoantenna arrays that generate Laguerre-Gaussian modes from a circularly polarized Gaussian input beam. The corresponding helical phase profiles ...
  • Limits of Babinet’s principle for solid and hollow plasmonic antennas 

    Horák, Michal; Křápek, Vlastimil; Hrtoň, Martin; Konečná, Andrea; Ligmajer, Filip; Stöger-Pollach, Michael; Šamořil, Tomáš; Paták, Aleš; Édes, Zoltán; Metelka, Ondřej; Babocký, Jiří; Šikola, Tomáš (Springer Nature, 2019-12-01)
    We present an experimental and theoretical study of Babinet’s principle of complementarity in plasmonics.We have used spatially-resolved electron energy loss spectroscopy and cathodoluminescence to investigate electromagnetic ...
