An artificial magnetic material with interdigital structure

An interdigital-cell-based metamaterial is introduced, which is more compact than SRR-based and CLL-based cells. A numerical experiment setup is proposed to simulate the transmission characteristics of the waveguide filled with this kind of metamaterial. The numerical results show that passbands exist at frequency range corresponding to the negative permeability frequency range of the filling metamaterial, and is much lower below the TE₁₀ cutoff frequency of a hollow waveguide with the same size. Issues such as power capacity, attenuation characteristics and conversion from/to normal waveguides will be discussed in future work.
