An integral equation based on a plane wave representation of the fields in a simply connected and anisotropic medium has been derived in order to handle the problem of two-dimensional scattering by a homogeneous anisotropic cylinder Its simplicity: one-dimensional, finite range of integration, one unknown with no derivatives of it involved, and a nonsingular kernel, results in an efficient and straightforward numerical implementation Both polarizations are considered and computer results are presented, discussed, and used to check our scheme thoroughlyread more

Anisotropic mass density by two-dimensional acoustic metamaterials
TL;DR: In this paper, a new class of acoustic metamaterials characterized by a dynamical effective mass density that is anisotropic is presented. But the analytical expressions for the dynamical mass density and the effective sound velocity tensors are derived in the long wavelength limit, showing an explicit dependence on the lattice filling fraction, the elastic properties of cylinders relative to the background, their positions in the unit cell and their multiple scattering interactions.
