英文摘要	We construct new three-dimensional fractal acoustic metamaterials by adopting Menger structure, which have the double-negative property with a single structure. By adopting the finite element method and S-parameter retrieval method, the effective parameters of the acoustic metamaterials with different fractal orders are researched separately. The results show that with the increase of the fractal orders, the frequency ranges of negative effective parameters become wider. Furthermore, with the increase of the fractal order, the structure become lighter, which shows a promising application in engineering.
