  • Comparative study of plasmonic antennas fabricated by electron beam and focused ion beam lithography 

    Horák, Michal; Bukvišová, Kristýna; Švarc, Vojtěch; Jaskowiec, Jiří; Křápek, Vlastimil; Šikola, Tomáš (Springer Nature, 2018-06-25)
    We present a comparative study of plasmonic antennas fabricated by electron beam lithography and direct focused ion beam milling. We have investigated optical and structural properties and chemical composition of gold ...
  • Imaging of near-field interference patterns by a-SNOM – influence of illumination wavelength and polarization state 

    Dvořák, Petr; Édes, Zoltán; Kvapil, Michal; Šamořil, Tomáš; Ligmajer, Filip; Hrtoň, Martin; Kalousek, Radek; Křápek, Vlastimil; Dub, Petr; Spousta, Jiří; Varga, Peter; Šikola, Tomáš (Optical Society of America, 2017-07-05)
    Scanning near-field optical microscopy (SNOM) in combination with interference structures is a powerful tool for imaging and analysis of surface plasmon polaritons (SPPs). However, the correct interpretation of SNOM images ...
  • 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 ...
