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 ...
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 ...
Independent engineering of individual plasmon modes in plasmonic dimers with conductive and capacitive coupling
(WALTER DE GRUYTER GMBH, 2020-03-01)
We revisit plasmon modes in nanoparticle dimers with conductive or insulating junction resulting in conductive or capacitive coupling. In our study, which combines electron energy loss spectroscopy, optical spectroscopy, ...
