Acoustic Cloaking

Application ID: 3867

This example demonstrates how to use a background field in a sound scattering problem. The application is an acoustic invisibility cloak made of a metamaterial. Two different types of metamaterials are used, one using an anisotropic acoustic material with varying properties and one using two layered materials with varying properties. Thanks to its space-dependent material properties and layered structure, both types of metamaterials are almost transparent to an incident plane pressure wave.
