A complete, plane wave spectral, vector wave function expansion of the electromagnetic, electric, and magnetic, dyadic Green's function for electric, as well as magnetic, point currents for a planar, multilayered, symmetric gyroelectric medium, where the gyroelectric anisotropy is confined in the plane parallel to planar interfaces is presented. It is given in terms of z-propagating, source-free vector wave functions, where i is normal to the interfaces. It is shown that, because of the reflection symmetry of the electric permittivity tensor, where the modes are decoupled, an efficient representation of the field within each of the layers is possible. Some salient features of the Green's dyadic, along with a physical interpretation, are also described.
