In Sees. 2.1.2 and 3.4.2 it was shown how Lorentz reciprocity in physical space led, via Kerns’ formulation and its generaliztion to include eigenmodes within anisotropic media, to a scattering theorem in plane-stratified systems (‘reciprocity in k-space’). In this chapter we consider the reverse derivation. Our starting point is the scattering theorem (2.112) for the plane-stratified medium (which for concreteness is taken to be a magnetoplasma), and from it we shall derive the Lorentz-reciprocity theorem, (4.89) and (4.91), relating currents and fields in a given medium and their mirror images, with respect to a magnetic meridian plane, in a conjugate medium. Since the plane-stratified magneto-plasma is self-conjugate, as we have seen in Chap. 2, all fields and currents, given and conjugate, are located in the same medium.
