Abstract
A perturbation theory is presented, providing a simple description of the S wave from a centre of expansion and the P wave from a centre of rotation. The relationships between the directivities of these waves and polarization anomalies of plane waves are established. The effect of anisotropy on the generation of these waves is compared with that of a smooth inhomogeneity.
