'Acoustic Cloaking': A Reality?

August 2008
Mix;Aug2008, Vol. 32 Issue 9, p64
The article reports on results of the study "Acoustic cloaking in two dimensions: A feasible approach," by Daniel Torrent and Jose Sanchez-Dehesa of Wave Phenomena Group, Department of Electronics Engineering at the Polytechnic University in Valencia, Spain. The study showed that metamaterials constructed with sonic crystals can be designed to produce an acoustic cloak to make objects impervious to sound waves.
