Abstract :
The use of an array of circumferential slots in the outer conductor of a dielectric-clad coaxial cable as a new way to launch a TM0 surface wave on a Goubau line is described. Its advantage over a conical horn lies in its efficiency depending only on its length, which makes it particularly suitable for use in a high-speed ground transportation system.
