Simulation determination of the negative permeability for the metamaterials based on Sr(ZnTi)Fe10O19 hexaferrite

Negative magnetic permeability of the novel metamaterial structures based on a M-type hexaferrite (Sr(ZnTi)Fe 10 O 19 ) was determined by simulation methods, in the frequency range of 5-24 GHz. The results completes the measurements performed for a particular structure (Liu et al., 2007) and are poi...

Summary:Negative magnetic permeability of the novel metamaterial structures based on a M-type hexaferrite (Sr(ZnTi)Fe 10 O 19 ) was determined by simulation methods, in the frequency range of 5-24 GHz. The results completes the measurements performed for a particular structure (Liu et al., 2007) and are pointing out the tunability of the structure and of the corresponding electromagnetic parameters by varying the bias field H and the substitution ions content. The simulation strategy was conceived to reproduce the metamaterial structure consisting of the hexaferrite and a metallic wires array, based on the results obtained in our previous studies of magnetic metamaterials. The test configuration was represented by the metamaterial samples filling a rectangular waveguide excited by the TE 10 mode, where the S-parameters were given by the HFSS program. The passband was obtained in the domain of 6.4-12.8 GHz, depending on the metamaterial structure.
