Angle-dependent ultrasonic transmission through plates with subwavelength hole arrays.
We study the angle and frequency dependence of sound transmission through water-immersed perforated aluminum plates. Three types of resonances are found to govern the acoustic properties of the plates: lattice resonances in periodic arrays, Fabry-Perot modes of the hole cavities, and elastic Lamb modes. The last two of them are still present in random arrays and have no parallel in optical tran...
متن کاملextraordinary transmission through subwavelength hole arrays
The recent history of the research and development around plasmon surface waves that was initiated by the work published in Nature in 1998 by Ebbesen et al. [1] looks like a ten-fold compressed version of studies initiated more than a century ago by Robert Wood with his discovery of anomalies in the efficiency of metallic diffraction gratings, now known as Wood’s anomalies [2]. In 1902, R. Wood...
متن کاملUltrasonic transmission through multiple-sublattice subwavelength holes arrays.
The ultrasonic transmission through plates perforated with 2 × 2 or 3 × 3 square array of subwavelength holes per unit cell are studied by numerical simulations. Calculations are obtained by means of a theoretical model under the rigid-solid assumption. It is demonstrated that when the inter-hole distance within the unit cell is reduced, new transmission dips appear resulting from Wood anomalie...
متن کاملTheory of extraordinary optical transmission through subwavelength hole arrays.
We present a fully three-dimensional theoretical study of the extraordinary transmission of light through subwavelength hole arrays in optically thick metal films. Good agreement is obtained with experimental data. An analytical minimal model is also developed, which conclusively shows that the enhancement of transmission is due to tunneling through surface plasmons formed on each metal-dielect...
