Dispersion Characteristics of a Waveguide with Glide Reflection Symmetry

摘要

An exact formulation of the boundary value problem for an infinite lossless iris loaded periodic waveguide with glide reflection symmetry has been obtained for TM wave propagation. The characteristic equation for the fundamental propagation constant gamma is solved for real as well as complex roots. These solutions are plotted in the form of k-beta diagrams. The effect of variation of certain parameters is studied. On the basis of the periodicity of the solutions for gamma it is demonstrated that the effective period of this structure is half of its translation period. A discussion of the k-beta plots is presented and some comments on the properties of the complex waves in lossless periodic waveguides are included. (Author)
