To directly map the amplitude and phase of localized surface plasmon polariton resonances in nanoscopic particles using purely optical techniques.
Applied apertureless scanning near-field optical microscopy (aSNOM) under ambient conditions.
Implemented polarization control to record real-space optical near-field distributions of bare resonant nanostructures.
Successfully mapped dipolar and quadrupolar localized surface plasmon polariton modes with high fidelity in both amplitude and phase.
Demonstrated reliable, in situ optical inspection of higher-order resonant plasmonic modes without perturbation.
