Arrays of subwavelength holes in metal film show enhanced transmission when compared to what is expected from classical diffraction. It appears that this phenomenon is crucially related to surface plasmon polaritons. By their nature, surface plasmon polaritons are particularly sensitive to the optical properties of the metal film. In this work we relate in the optical regime these properties on the enhanced transmission.
