review text: We introduce a new generalisation of the conventional volume source, or polarisation source, formulation of diffraction of scalar linear wave motion. The phase-integral, or Liouville-JWKB, principle is incorporated in such a way that a sequence of approximations is readily developed. The levels of the approximations, and the norms of the associated integral operators, are listed.
