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. Roy Lewallen, W7EL Crazy George wrote: Gobau? After 24 hours, the name came. Maybe another 48 and I can spell it correctly. -- Crazy George The attglobal.net address is a SPAM trap. Please change that part to: attdotbiz properly formatted. |
