fa Hybrid mode tunability in metamaterial waveguides تخصصی Special پژوهشي Research In this paper, the tunability of hybrid modes frequency region is studied in slab metamaterial-dielectric waveguides by considering different structural parameters. In this case, the effect of metamaterial structural parameters such as the magnetic oscillation strength and magnetic damping are studied. We can see that with a decrease in the magnetic oscillation strength, the negative refractive index region decreases.
