Abstract

This article presents an analysis of electromagnetic wave propagation in a model of rectangular waveguide when filled with a double-negative metamaterial. The field components and dispersion relation of the electromagnetic waves are calculated, analytically. The dispersion relation is numerically analysed by plotting the normalized squared phase velocity against the propagation frequency for the variation of the parameters of the waveguide and the wave. The dominant mode is found to be TE10 mode. The dispersion curves show propagation and non-propagation characteristics for larger dimensions and for dominant mode. Some aspects were found to be much different from a conventional rectangular waveguide.
