    "abstract": "If all space is occupied by a linear bianisotropic material--whether\nhomogeneous or not--then the concurrent replacements of the permittivity and\nthe impermeability tensors by the negatives of their respective complex\nconjugates and of the magnetoelectric tensors by their respective complex\nconjugates (in the Boys-Post representation) imply the conjugation of both E\nand H, in the absence of externally impressed sources. This conjugation\nsymmetry in linear electromagnetism has observable consequences when the linear\nbianisotropic material occupies a bounded region.",
