May 05, 2017??? In the one about radiating cables it treats the cables as an "array of magnetic dipoles, oriented along the cable axis". The azimuthal component of the electric field is then computed. For coupled mode, on the other hand, the cable is compared to a long electrical antenna and they calculate the radial component of the electric field.
