Fano resonances in plasmonic nanoparticle aggregates
We investigate the plasmonic properties of a symmetric silver sphere septamer and show
that the extinction spectrum exhibits a narrow Fano resonance. Using the plasmon …

Mechanically tunable nanogap antennas: single‐structure effects and multi‐structure applications
F Laible, A Horneber, M Fleischer - Advanced Optical Materials, 2021 - Wiley Online Library
By mechanically changing the width of a nanometer gap between two optical antennas, the
coupling condition for the antennas can be seamlessly modified. This leads to a shift in the …
