Single conductor surface wave transmission line system for terminating E field lines at points along the single conductor
First Claim
1. A surface wave transmission line system, comprising:
- a single conductor having a cross-sectional dimension;
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 when a surface wave is launched on said conductor, in regions removed from said first and second launchers at least several hundred times the greatest cross-sectional dimension of said conductor, all E-field lines emanating from said conductor terminate at E-field termination points located along said conductor;
wherein said conductor is radially symmetrical and has a generally uniform longitudinal cross section such that in regions far from said conductor, E-field lines emanating from or terminating onto said conductor from opposite sides cancel one another.

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.
