文摘
In this work we study the way light interacts with thin gold films perforated with periodic arrays of holes with diameter smaller than the wavelength of the incident light. This structure exhibits sharp peaks in transmission spectra, at wavelengths larger than the array period, with efficiencies of orders of magnitude greater than predicted by standard aperture theory. The effect is highly dependent upon the structural film parameters like hole diameter and film thickness.
