Technology Review: Blogs: arXiv blog: Acoustic superlens could cloak objects from sonar

University of Illinois researchers have developed a method for bending sound waves using metamaterials that holds the promise of being adapted for a sonic cloaking device. The device was originally developed as a sonic superlens, but the approach can, in principal be adapted to cloak an object from sonar.
