Duke University Models Metamaterial Structures for Acoustic Cloaking

Steve Cummer, Electrical and Computer Engineering Department, Duke University, USA

Researchers at Duke University are using numerical modeling to develop metamaterial structures for acoustic cloaking. Steve Cummer, professor of electrical and computer engineering, explained that the acoustic metamaterial designs are optimized through numerical simulations, which are then translated into modern fabrication techniques and experimentally tested. The COMSOL Multiphysics® software enabled Cummer and his team to iterate designs more quickly and identify factors that can be adjusted to hit specific targets.
