Fig. 1. Near-infrared transmittance spectra of a gold 200-nm-thick film in air perforated by a 2D hole array (hole area fraction of 0.08). The results hold for an array pitch, a = 0.94 µm, and for a normally-incident illumination. Symbol λ denotes the wavelength of light. The green curve (--) represents results of a fully vectorial model combining the contributions of the surface-plasmon-polariton (SPP) to the transmittance and a quasi-cylindrical wave (Liu H et Lalanne 2008) and the red curve (--) represents only the SPP contribution (Ebbesen TW et al 1998).
