摘　　要：We demonstrated a two-dimensional quasi-crystal dendritic structure model with negative permeability.The microwave transmission and reflection properties of periodic and quasi-crystal dendritic structure mediums with varied angle incidence were measured.The results showed that the resonant peaks of quasi-crystal negative permeability samples and left-handed samples had tiny shift with the altering of incident angle.Because of the influence of coupling between quasi-crystal dendritic cells,the resonance of the entire material was enhanced or weakened.The quasi-crystal dendritic structure model will provide an easy method to design isotropic left-handed materials(LHMs).We demonstrated a two-dimensional quasi-crystal dendritic structure model with negative permeability.
