Reflection and Refraction of Elastic Waves
So far we have considered plane elastic waves in a homogeneous unbounded crystal, which is an idealized case, because we virtually always have waves in a crystal of restricted dimensions. This means that we have to consider the behavior of elastic waves at the surfaces bounding a crystal, which is much more complicated than the problem of waves in an unbounded homogeneous crystalline medium . For this reason we shall consider only the behavior of plane waves at an infinite plane boundary, on both sides of which lie unbounded homogeneous media differing in density and elastic properties.
