Acoustic Cloaking
Model ID: 3867
Two articles in the New Journal of Physics describe how to derive necessary conditions on an anisotropic density tensor to create a perfect acoustic cloak in 2D, and show how this material can be realized in practice as a layered shell with isotropic properties in each layer.
These two example files illustrate simplest possible implementations using both anisotropic density and the layered shell approach as described in the two papers.
