|Title||Characteristics of left-handed multilayer slab waveguide structure|
We examine analytically the propagation of TE-polarized waves in a four-layer slab waveguide structure. One of the layers is considered as a Left-handed or metamaterial with simultaneously negative ε and µ. The dispersion relation of such a structure is shown in terms of the normalized thickness and the asymmetry factors. The effect of the doubly negative material parameters on the propagation characteristics has been examined. The variation of the effective index of the structure with different parameters of the layers is studied extensively. A comparison of the structure under consideration with the conventional right handed four-layer waveguide structure is also shown.
