Resumen:
Extraordinary transmission and other interestingrelated phenomena for 1-D periodic arrays of slits (compounddiffraction gratings) have recently been the object of intenseresearch in the optics and solid state physics communities. Thiscase should be differentiated from the extraordinary transmissionthrough arrays of small apertures on metal screens sincesmall holes only support below-cutoff modes, whereas slits canalso support transverse electromagnetic modes without cutofffrequency. In this paper, an equivalent-circuit approach is proposedto account for the most relevant details of the behavior ofslit-based periodic structures: extraordinary transmission peaks,FabryPérot resonances, and transmission dips observed in compoundstructures. The proposed equivalent-circuit model, basedon well-established concepts of waveguide and circuit theory,provides a simple and accurate description of the phenomenonthat is appropriate for educational purposes, as well as for thedesign of potential devices based on the behavior of the structuresunder study.
