Research output: Contribution to journalConference articleResearchpeer-review


By structural engineering of sub-wavelength apertures, we numerically demonstrate that transmission through apertures can be significantly enhanced. Based on equivalent circuit theory analysis, structured apertures are obtained with a 1900-fold transmission enhancement factor. We show that the enhancement is due to the excitation of the strong localized resonant modes of the structured apertures.
