V. Daniele et al., SPECTRAL THEORY OF A SEMIINFINITE TRANSMISSION-LINE OVER A GROUND PLANE, IEEE transactions on electromagnetic compatibility, 38(3), 1996, pp. 230-236
The electromagnetic modeling of wave propagation along a semi-infinite
wire with ground return is addressed. External excitation, via plane
wave is considered. Both wire and ground plane are assumed to be perfe
ct conductors, Through a spectral approach, a one-port Thevenin model
of the structure, valid for any distance between wire and ground, is d
eveloped, such a model allows to evaluate rigorously the limits and th
e accuracy of the transmission line (TL) equations.
