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.
