Nondiffracting waves in anisotropic media.
Recently the physics of ballistic phonon propagation in anisotropic crystals has been studied with new phonon-imaging methods. In this paper we consider nondiffracting waves that can propagate in anisotropic crystals and analyze their properties that emerge specifically due to the anisotropy. We further present a detailed generation and detection scheme for the experimental verification of the wave modes considered.
