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.

There was a glint from my laptop's LCD screen that distorted the title, and my brain automatically read "Artistic superheroes could cloak objects from sonar" and went "Cool!"

I'm not sure whether my automatic fiction or the fact is cooler.

Makes one wonder how being an artistic superhero allows them to cloak things. Paintbrush of power? Songs of sonic disruption?

I like the songs of sonic disruption. Does possessing a super-powered object (such as a paintbrush) still make one a superhero?
