THE PROPAGATION AND CUTOFF FREQUENCIES OF THE RECTANGULAR METALLIC WAVEGUIDE PAR- TIALLY FILLED WITH METAMATERIAL MULTILAYER SLABS

In this paper, the wave propagation and the cutoff frequencies of a rectangular metallic waveguide, partially filled the metamaterial multilayer slabs have been studied. The equations of the TMM method are not complex and the numerical examples show that we can easily obtain the characteristics of the metamaterial multilayer’s rectangular waveguide satisfyingly. The cutoff frequencies of the metamaterial waveguide show very different characteristics compared with the usual waveguide.
