Abstract

It has been recognized for several years that the highly anisotropic intensity patterns associated with phonon focusing should undergo radical changes as the phonon wave vectors approach the Brillouin zone boundary [1–4]. This is simply a consequence of the distortion of the acoustic slowness surfaces in the dispersive regime. Phonon focusing patterns of Large-<Inline>1</Inline> phonons must contain detailed information about the curvatures of the slowness surfaces, and thus they provide a potentially new tool for gauging the validity of lattice-dynamics models.
