Line Plot from Scientific Research

Experimentally measured resonance energy of an Au nano-object with a diameter of 6 nm inside a nanocavity for different nanoprobe diameters (pink circle). The blue-to-red colored lines are the simulated extinction cross-section spectra of a 6 nm nano-object inside a plasmonic nanocavity. The black lines are based on a strongly coupled resonator model. The resonance of the nano-object on the Au film is the green dashed line, and that of the nanoprobe on the film is the gray dashed line.
