Abstract
In a recent paper, the Helmholtz method of potentials was generalized for application to the vector wave equation of elasticity for certain types of inhomogeneous media. Only the cases of three-dimensional axially symmetric waves and two-dimensional waves were treated. It is shown in this letter that these restrictions on wave symmetry can be removed, so that the method is applicable for waves of general spatial variation.
