Abstract
Fishnet structures provide a popular procedure to obtain negative-refraction index artificial media. They are basically stacked extraordinary-transmission structures that are closely spaced. Thus these structures can be built by combining two or more metallic plates with a 2D periodic distribution of small apertures. Analytical models based on equivalent circuits are almost trivially obtained when the electric separation between metal plates is relatively large.
However the more interesting situation arising from tightly coupled screens is more involved and only heuristic equivalent-circuit approaches have been reported in the literature. In this contribution a systematic approach to obtain a general circuit model for this kind of structures is developed.
