Abstract :
The purpose of this work is to investigate the possibility of supporting LH propagation in rectangular waveguides with dielectric-filled broad wall corrugations. In this paper, spectral analysis of a corrugated waveguide is performed based on the dyadic Green´s function approach in conjunction with Floquet´s theorem analysis of periodic structures to determine the dispersion characteristics and modal field distribution.
