摘要： The self-similarity, high geometric symmetry and spatial utilization properties of fractal structures provide new methods for the development of absorbing metamaterials. In this paper, the microwave absorption properties of the gradient dendritic fractal metamaterial structure (GDFMs) based on carbon black and acrylonitrile-butadiene-styrene composites were investigated. The optimal metamaterial structure has an effective absorption in the frequency range of 4.5-40 GHz. The rotational-symmetry GDFMs leads to the polarization independence, and the GDFMs exhibits a wide-angle absorption performance for both TE and TM waves. It is expected that the proposed GDFMs has good application prospects in electromagnetic wave absorption.
