“…The achievement of perfect transmission at resonant frequencies has also been reported [6,7]. Moreover, the transmission properties of random and quasi-periodic MHAs in the terahertz region have been analyzed both experimentally and theoretically [8][9][10][11]. Detailed research has been carried out on the role of long-and short-range orders in the transmittance spectra of quasi-periodic MHAs [7,11].…”

By using coupled-mode analysis, we investigate numerically the extraordinary optical transmission (EOT) of incommensurate metal hole arrays (IMHAs) in the terahertz region to study how the degree of long-range and short-range orders affect EOT. In IMHAs, the holes of one set of metal hole arrays (MHAs) are regarded to work as impurities to the holes of another set of MHAs. Therefore, the transmittance spectra are expected to be significantly modified from those of the constituent MHAs. It is found that the resonance transmission frequencies of IMHAs almost coincide with those of the composite MHAs despite the fact that the surface waves of each MHA are mutually perturbed strongly due to the presence of short-range disorder. This indicates that the presence of longrange order is essential to establish EOT. These observations allow more flexible design of narrow bandpass filters in the terahertz region.

“…The surface atoms are re-arranged, resulting in chemistry and structure changes. Therefore, the fabrication technique is virtually independent of the materials under processing, and can be applied to a variety of materials-hard, soft, or combinations thereof [14][15][16]. However, with respect to the application in silicon photonic devices, this technique has an intrinsic inconvenience-the specimens inevitably suffering a certain amount of damages, as they have to be exposed to a highly accelerated ion beam.…”
