Introduction
============

line communication (PLC) is nowadays a widespread and compelling technology to convey information both in the context of Smart Grids and In-Home environments [@lampe2016power]. Its intrinsic property of using the existing cable infrastructure has the advantage for utilities of being proprietary and for residential users of granting wider range and possibly higher coverage compared to WiFi technologies. On the other side, power lines are made of metallic cables that inherently radiate power when excited with a current signal, i.e. whenever a PLC signal is transmitted. Although this phenomenon is known by the PLC community since its foundation, dealing with it has always been challenging [@Berger:2014:MPL:2636789 Part II]. Among the papers about this topic, [@kikkertradiation] presents a characterization of the radiation pattern in simple distribution lines, while [@paganireversal] presents a signal processing technique to reduce the radiated emission. However, to date a thorough characterization of radiation phenomena in power line networks is still missing. A proof of this is the fact that PLC standards fix transmission power limits based on empirical procedures [@7867791].

In this paper, we want to propose a comprehensive model of power line
