| Abstract: | A novel metamaterial unit with simple structure,low loss and broad stopband was proposed.Through analyzing the equivalent circuit of the unit,the effects of structure parameters of the unit on the travel of electromagnetic wave were investigated,and the equivalent permeability and permittivity of the unit were extracted using the S-parameter retrieval method.This not only shows the band-stop mechanism of the unit but also further proves the reliability of the equivalent circuit and analysis.A waveguide high... |
