Abstract :
Assessing the near-field distribution of plasmonic nanoantennas offers fundamental insight into light-matter coupling. In particular resonantly enhanced near-field intensities in the IR and THz region are important since the molecular fingerprints of various molecules are situated in this spectral domain.
