A transformation linking spherical multipole fields with generalized spheroidal multipole fields is derived.
Applications including the inverse diffraction problem for spherically scanned near-field data for sources that due to conformal considerations are efficiently described using spheroidal (either oblate or prolate) volume support regions are discussed with the aid of numerical illustrations.
