The paper is devoted to the ray-theory approximation of electromagnetic waves propagating in heterogeneous bianisotropic media. We consider the anisotropic ray theory in which the two electromagnetic waves differing by their polarizations are strictly decoupled and propagate with sufficiently different velocities. We develop the ray theory in terms of the magnetic vector potential with the Weyl gauge (zero electric potential).
