AT Collections – Acoustic Metamaterials
Acoustic metamaterials manipulate effective material properties influencing wave propagation in a manner not commonly found in nature. Based on the historic foundation of wave propagation in periodic structures, metamaterials have been developed for noise control, acoustic cloaking, and can even explain certain phenomena in woodwind instruments. This collection includes articles that touch on ancient history and propose new directions for this unexpected application of acoustics.

Acoustic Metamaterials – by Michael R. Haberman and Andrew N. Norris
Acoustic metamaterials expand the parameter space of materials available for new acoustical devices by manipulating sound in unconventional ways.
Acoustic Cloaking – Andrew N. Norris
It might drive bats batty, but there is no fundamental physical limitation on developing acoustic cloaking devices.
