PROPAGATION OF MICROWAVES ON A SINGLE WIRE Part IV

Abstract

A theoretical study of the reduction in phase velocity and radial field spreadof the Harms-Goubau Jine, as a function of the wire radius, coating thickness anddielectric constant for different wavelengths, has been carried out. It is observed that the dielectric coating thickness has more control over the spread of the field in the radial direction than the dielectric constant of the coating. The percentage of the total power flowing in the dielectric coating, as a function of the coating thickness and dielectric constant for three wavelengths has been calculated.These results when compared with that of the Sommerfeld line show clearly the superiority of the Harms-Goubau line as a surface wave guide.
