Abstract

The electromagnetic wave perfect absorption of metamaterial is focused on by scientists currently. Conventional studies typically use a basic unit cell and then develop the entire structure in production. In this paper, we study and use a full-sized twisted metamaterial structure with the expectation that this structure will reveal outstanding advantages and possess excellent electromagnetic absorption properties. The structure of the twisted metamaterial consists of two coincident layers of cyclic lattice stacked on top of each other. When one lattice layer rotates at a specified angle relative to the other, it generates a new lattice configuration and increases the absorption of the structure. Therefore, the frequency band widens up to 6 GHz.
