Abstract
We present a semi-analytical model that quantitatively predicts the transmi ssion, the absorption and the resonance locations of one-dimensional lamell ar metallic gratings with subwavelength slit apertures. The model relies on the fact that subwavelength apertures perforated in metallic films behave like monomode waveguides and provide Airy-like formulae for the transmissio n and reflection coefficients. Limitations are outlined for too shallow gra ting depths.
