PROPAGATION OF MICROWAVES ON A SINGLE WIRE -PART I

Abstract

Some quantitative measurements on cylindrical surface waves excited on a cylindrical bare copper conductor have been made at 3.2 cm. wavelength.The results on radial field measurements indicate fair agreement with results predicted by theory. The decay coefficient for the radialfield is 140 1/m'. It is suggested that the surface conductivity of metals in the form of wire can be found at microwave frequencies by using thismethod. Field distributions near the launching horn have been found to be considerably distorted due probably to the presence of complementary waves  The design and constructional details of the launching system, probe, etc. used in the experiment are presented.
