Abstract
The present invention relates to a three-dimensional metamaterial capable of attenuating acoustic waves and mechanical vibrations in broad low-frequency ranges. The three-dimensional metamaterial comprises multiple unit cells that form a three-dimensional lattice. The unit cells each comprise a central part and six satellite parts that are equally distributed around the central part. Each unit cell is connected to the central part by at least one corresponding connector. The invention further relates to a unit cell of a three-dimensional metamaterial capable of attenuating acoustic waves and mechanical vibrations in broad low-frequency ranges.
