Calculated scattering cross-section ratio of Au nano-object inside a nanocavity (red circle). The averaged electric field over the area of the nano-object | E | 4 in the gap of an empty nanocavity (green circle). The inset shows the electric field distribution of a nano-object in the nanocavity. The nanoprobe diameter is 80 nm, and the scale bar is 20 nm.
