摘要：

In this letter, we consider the scenario that a linearly polarized electromagnetic plane wave excites a transmission line (TL). By tailoring the reciprocity theorem for modeling the field-coupling problem, we prove that the maximal/minimal coupling scenarios can be determined from the radiation pattern data. Particularly, the incidence and polarization angles of the field that maximize/minimize the coupling efficiency of a matched TL are solved in a closed form. Accordingly, design guidelines have been proposed for the protection of TL from electromagnetic interferences.
