The paper deals with two different approaches for the analysis of electromagnetic field coupling to finite length buried conductors based on the wire antenna theory (AT) and the transmission line (TL) method, respectively. The wire antenna formulation deals with the corresponding set of Pocklington integro-differential equation, while the transmission line model uses the Telegrapher's equations. The set of Pocklington equations is solved via the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM), while the transmission line equations are treated using the chain matrix method and modal equation to derive per unit length parameters. Some illustrative numerical results for the frequency response of several configurations of buried conductors, obtained via different approaches, are given in this paper.
