Abstract

In this article, we present an analysis of electromagnetic wave propagation in a parallel-plate waveguide filled with (a) a conventional (linear, homogeneous and isotropic) dielectric medium (b) metamaterials. In this connection, we derive the dispersion relations for the TE and TM wave modes for both cases. The dispersion characteristics of the waves are obtained by the numerical analysis of the dispersion relation by plotting it for the propagation frequency versus the wave vector for different values of the dimensions of the waveguide and the number of modes. The dispersion characteristics show propagation and non-propagation regions in the microwave frequency range. This effect can be used for different waveguide applications e.g. filters, sensors etc.
