EXPERIMENTAL STUDY OF UNIFORM AND CORRUGATED ROD AS SURFACE WAVEGUIDE AND AS RADIATOR.

Abstract

Experimental results are presented on the radial and axial field distributions and hence radial decay coefficient, guide wavelength and also radiation patterns and gain as functions of spacing, depth of grooves, diameter and length of a corrugated rod and also as functicns of diameter and length of  a uniform rod, both the rods being excited in E&sub0 —mode. The characteristics such as scattering parameters and hence launching efficiency, etc. of mode transducer used for exciting the uniform and corrugated rods are also determined.
