Characteristics of Discrete Propagation Modes on a System of Horizontal Wires over a Dissipative Earth.
Abstract
An equation for determining the propagation constants of the discrete modes of propagation on a system of m parallel thin wires above a dissipative earth is derived. Approximations to the Sommerfeld integrals involved in the modal equation that are accurate for relatively large values of the earth's refractive index are found and rigorous errors bounds for these approximations are obtained. Plots of the complex propagation constants for a dual bare wire line are calculated. A degeneracy is shown to exist between the two bifilar modes and in addition, one of the bifilar modes is seen to disappear into the improper Riemann sheet for small spacings between the two wires.
