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 ...
