Close. It's Goubau, from "Surface Waves and Their Applications to
Transmission Lines," J. Appl. Phys., vol. 21, 1950. An interesting
variation is described in "Low-Loss RF Transport Over Long Distances",
by M. Friedman and Richard F. Fernsler, IEEE Trans. on Microwave Theory
and Techniques, Vol. 49, No. 2, Feb. 2001, describing a system the
authors describe as "simple, inexpensive, lightweight, and [having] low
attenuation". They used a strip of aluminum foil 6 cm wide and 0.02 mm
thick with periodic punched holes as the line, strung it around a lab
with the strip suspended by threads, and measured low attenuation. How
this could translate to a practical outdoor system for "long distance RF
transportation" as the authors claim is beyond my feeble imagination.

In a Beverage antenna, how much transmit power is lost in the
terminating resistor? We know a Beverage is a very inefficient
transmitting antenna. Could it be because it's a fairly efficient
transmission line? Or is it because of ground losses?
