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, ...
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 ...
