Electromagnetic interference from carrier channels on finite-length power lines above a lossy ground in a wide frequency range

Prediction models of the electromagnetic interference generated by carrier channels on multiconductor power distribution lines wth non-radiating terminal loads are presented. The proposed formulations are addressed to the evaluation of the radiated field components in a wide f?equency-range, by including the effects of the lossy ground plane and removing the hypothesis of unidirectional current propagation. The validity of the infinite-length approximation and of the complex image approach are investigated, with reference to different line-configuration, in case of wire-toground and wire-to-wire signal transmission.
