Modal Representation a Horizontal Wire Above a Finitely Conducting Earth.
Abstract
The modal representation of the fields of a thin horizontal wire (with or without dielectric coating) above the surface of a finitely conducting earth is discussed. A general expression for the excitation of the discrete modes by an aperture field of arbitrary form in the transverse plane is given. As a consequence, it is proved that any discrete mode can be excited with high efficiency with an aperture of finite size. The dependence of the discrete modal propagation constants of the discrete modes upon various physical parameters is investigated in some detail and the possibility of mode degeneration is demonstrated. Field plots of the discrete modes are presented which show the qualitative differences between the so-called 'transmission-line' mode and the recently discovered 'earth-attached' mode. (Author)
