The theory of uniaxial bi-anisotropic media: The quasi-static case

The problem of unbounded uniaxial bi-anisotropic media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are then determined. The similar problem of static electric and magnetic current sources with the goal of finding the electromagnetic fields is carried out. It is observed that either of static electric or magnetic point charge produces both electric and magnetic fields. Furthermore, it is observed that only the transverse components of current sources with respect to axis of the medium produce the axial field components.
