Optical transmission theory for metal-insulator-metal periodic nanostructures

Nanophotonics, 2016
A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layers with periodic one-dimensional ...
