Structure and dimension details.

Layers dimension	Material	Purpose
Top layer: length = 1000 nm, width = 1000 nm, thickness = 100 nm	Silver	Lights interact with the nanoholes which are etched in silver and create resonance.
Nanohole's in a silver layer, Diameter = 200 nm, period = 400 nm
Bottom layer: length = 1000 nm, width = 1000 nm, thickness = 950 nm	Titanium	Works as a substrate.
