INVESTIGATIONS ON CORRUGATED SURFACE WAVE LINE

Abstract

The characteristic equation for a surface wave line loaded with uniformly spaced thin metallic discs excited in E0 mode has been derived. The effects of spadng and groove depth on field distributions have been studied, Considering the existence of only the fundamental mode, the radial field distribution curves as a function of grooves depth and spacing show the surface wave nature of the discs loaded structure. Solution of the characteristic equation shows the existence of pass and stop banks which have been represented graphically in the form of dispersion diagrams.
