Abstract
this paper has studied electromagnetic waves in planar dielectric waveguide containing left-handed medium propagate characteristics, the mode of transmission with left-hand materials is analyzed theoretically. Through the analysis of TE and TM wave in the transmission characteristics of planar dielectric waveguide, TE and TM mode dispersion equation are obtained, Concluded that the electromagnetic wave in the spread of the planar dielectric waveguide containing left-handed medium not only had oscillation wave and surface wave, traditional media planar dielectric waveguide only have the shock wave. Secondly, Simulation analysis has also been made on the propagation characteristics in slab waveguide with left-hand materials, Compared to traditional media planar dielectric waveguide, Planar dielectric waveguide containing left-handed medium compared with traditional planar dielectric waveguide possesses the advantages of larger bandwidth and less attenuation, then proved that this structure can be used as the transmission lines of microwave circuit.
