Abstract :
We investigate the coupling between localized resonance and lattice resonance in extraordinary transmission in metal hole arrays. The dominant mechanism of the extraordinary transmission changes continuously with a change in the length of the rectangular holes. We also study the effect of the incident beam diameter and surface condition on the transmission spectrum to show the important differences between the two mechanisms.
