Paper Abstract

We present a novel theoretical approximation for predicting the enhanced optical transmission properties through a periodic array of subwavelength square apertures in perforated metal films. We show that a Fabry-Perot resonance occurs in an effective resonant cavity whose dimensions are determined by the apertures' geometry and the decay lengths of the associated evanescent diffracted modes. This model demonstrates strong agreement to simulated results, and can be used to rapidly and efficiently design aperture arrays with specific transmission properties.
