A layer-multiple-scattering method for phononic crystals and heterostructures of such

Abstract
We present a computer program to calculate the frequency band structure of an infinite phononic crystal, and the transmission, reflection and absorption of elastic waves by a slab of this crystal. The crystal consists of a stack of identical slices parallel to a given surface; the slice may consist of multilayers of non-overlapping spheres of given periodicity parallel to the surface and homogeneous plates. The elastic coefficients of the various components of the crystal may be complex funct...

Nature of problem
Calculation of the complex band structure associated with a given surface of a phononic crystal, and of the transmission, reflection and absorption coefficients of elastic waves by a slab of the crystal parallel to the given surface. We note that the ordinary frequency band structure of the infinite crystal is contained within the complex band structure of any surface of the crystal.
