Imaging of near-field interference patterns by a-SNOM – influence of illumination wavelength and polarization state
(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
(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 ...
Comparative study of plasmonic antennas fabricated by electron beam and focused ion beam lithography
(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 ...
Invited Article: Direct phase mapping of broadband Laguerre-Gaussian metasurfaces
(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 ...
