Evaluation of Certain Transmission Line Forcing Functions.
Abstract
This study was undertaken to evaluate the relative importance of certain newly-discovered transmission-line forcing functions, the effect of which was expected to depend on the differences in line currents induced by incident electromagnetic waves. Straightforward calculation of these currents and their effects on typical lines showed that the apparent existence of these terms is due to an unconventional resolution of the currents into independent modes. Alternatively, it was found that the usual distributed series-voltage and shunt-current induced sources are generally necessary and sufficient to characterize external excitation of a line along its length. It was concluded that when the transmission-line component of the line currents is defined in the conventional manner, no new forcing terms are apparent.
