Guided Waves in a Left-Handed Material Guiding Film With a Ferrite Cladding

We investigate TE guided modes at microwave frequencies in an asymmetric waveguide structure with a left-handed material guiding layer surrounded by a linear dielectric substrate and a gyromagnetic ferrite cladding. The effect of the gyromagnetic ferrite layer parameters on the dispersion properties of the waveguide structure is investigated in details. It is found that the effective wave index of the structure is negative as if the overall structure is a left-handed material. A considerable effect of the gyromagnetic ferrite layer on the dispersion properties of the structure is observed. The power propagating in each layer is also studied.We investigate TE guided modes at microwave frequencies in an asymmetric waveguide structure with a left-handed material guiding layer surrounded by a linear dielectric substrate and a gyromagnetic ferrite cladding.
