Analysis of Extraordinary Transmission through Subwavelength Periodic Slits

Extraordinary transmission of light through a metallic avay of subwavelength slits is investigated with the help of a rigorous computational method for periodic structures Here, using a nrttlticonductor transmission line model, we reduce Marwell's equations to a set of transmission line eauations so that we can model the metallic loss and piasmonic behavior ofthe array. To verifl the method, we compare our results with those oblained by the transfer matrix method and dynamic dffiaction model
