English abstract:
We present an experimental and theoretical study of Babinetīs principle of complementarity
in plasmonics. We have used spatially-resolved electron energy loss spectroscopy and
cathodoluminescence to investigate electromagnetic response of elementary plasmonic antenna: gold
discs and complementary disc-shaped apertures in a gold layer. We have also calculated their response
to the plane wave illumination. While the qualitative validity of Babinetīs principle has been confirmed,
quantitative differences have been found related to the energy and quality factor of the resonances and
the magnitude of related near fields. In particular, apertures were found to exhibit stronger interaction
with the electron beam than solid antennas, which makes them a remarkable alternative of the usual
plasmonic-antennas design. We also examine the possibility of magnetic near field imaging based on
the Babinetīs principle.
