Surface wave transmission system over a single conductor having E-fields terminating along the conductor
First Claim
1. A low attenuation surface wave transmission line system, comprising:
- a bare and unconditioned conductor, wherein the conductor lacks dielectric or special conditioning;
a first launcher for receiving incident electromagnetic energy and propagating a surface wave longitudinally along and in the region immediately around said conductor; and
a second launcher spaced apart from said first launcher on said conductor;
wherein the transmitted wave is of frequency less than 5 GHz;
wherein in regions removed from said first and second launchers at least several hundred times the diameter of said conductor, the E-field lines which emanate from said conductor all terminate at E-field termination points located along said conductor.

Abstract
A low attenuation surface wave transmission line system for launching surface waves on a bare and unconditioned conductor, such as are found in abundance in the power transmission lines of the existing power grids. The conductors within the power grid typically lack dielectric and special conditioning. Accordingly, the present invention includes a first launcher, preferably including a mode converter and an adapter, for receiving an incident wave of electromagnetic energy and propagating a surface wave longitudinally on the power lines. The system includes at least one other launcher, and more likely a number of other launchers, spaced apart from one another along the constellation of transmission lines. The system and associated electric fields along any given conductor are radially and longitudinally symmetrical.
