Collimation of sound assisted by acoustic surface waves

Abstract

The discovery of the phenomenon of extraordinary optical transmission through a two-dimensional array of subwavelength holes in a metallic film1 has opened a new line of research within optics. The key role played by surface plasmons in transferring light efficiently from the input side of the metal film to the output region was soon realized. This fundamental knowledge enabled extension of this surface-plasmon ability to achieve extraordinary optical transmission and strong collimation of light in a single hole surrounded by a finite periodic array of indentations2. Here, we show how these ideas developed for electromagnetic radiation can be transferred to other classical waves such as acoustic waves.
