☑ Local Capacitor Model For Plasmonic Electric Field Enhancement

The electric field immediately below an illuminated metal film that is perforated with a hole array on a dielectric consists of direct transmission and scattering of the incident light through the holes and evanescent near field from plasmonic excitations. We show that the needed level.
