Reply to "Comments on `Unified theory of near-field analysis and measurement́"

Wacker comments on Berger's question, (see ibid., vol. AP-30, no. 6, p. 1268, 1982), concerning the usefulness of the special conformal transformations of the conformal group for near-field electromagnetic scanning problems. Wacker believes the special transformations may be useful in nonhomogeneous media and/or nonlinear systems.
