Grouping the first two, middle two, and last two terms of the right-hand side reformulates this relation as
(2.61)
which, using again , becomes
(2.62)
Finally, grouping the first two terms of the right-hand side of this relation yields
(2.63)
Similarly, the term in (2.57) becomes
(2.64)
Substituting now (2.63) and (2.64) into (2.57) finally yields the bianisotropic Poynting theorem:
(2.65)
where is the energy density,
is the Poynting vector, and
and
are the impressed source power densities, and
and
are the induced polarization power densities, respectively, which are defined by
