Abstract

We present an elegant application of formal catastrophe theory to phonon focusing phenomena in crystals. The standard analysis of phonon focusing breaks down near singular directions known as caustics. The theory we present, in addition to being numerically accurate, provides a qualitative picture of caustic surfaces which yields important new insights into the results of phonon propagation experiments. Supporting experimental evidence is also presented.
