Field Coupling Parameters for a Single Round Wire Close to a Ground Plane of Two Large Round Wires in Free Space

Abstract

The TEM response of a conventional two-conductor transmission line to an external electromagnetic field is characterized by certain quantities termed magnetic- and electric field coupling parameters. Values of these parameters for a line consisting of two small round conductors, or one small conductor above an infinite ground plane, have been determined previously. The report obtains simple expressions for the parameters when the round conductors are of arbitrary, but equal, radius. The error incurred in assuming the small-wire approximation is tabulated in the range 1.1 < or = rho < or = 10, where rho is the height/radius ratio of the single conductor above ground, or the spacing/ diameter ratio of the two equal equi-radius conductors.
