Radiation Mode Analysis of Negative Permeability Metamaterial

Résumé fourni par la source

The High Impedance Surface (HIS) or near-zero refractive index metamaterials are used extensively to enhance the antenna performance or radiate directly. However, the radiation characteristic of negative permeability metamaterial has not been focused. We verify the corresponding radiation mode by using the negative-permeability split-ring resonator (SRR), where the related radiation modes are the same as the resonant modes. And a modified rectangular waveguide is fed to the unit cells to indicate the radiation performance.
