▎ 摘　　要

A polarization-independent broadband metamaterial absorber having graphene layer is proposed in this study. It is found that the absorption spectrum of the absorber becomes more promising after using graphene layers. Graphene layer increases the device robustness and stability of the device. The proposed absorber works for a wide operating region covering near ultraviolet to near infrared, i.e., 200-1792 nm. Absorption characteristics including the operating wavelength and the polarization nature of various existing absorbers is compared with the proposed absorber. It is noticed that the proposed absorber is physically realizable since it has a sufficiently large geometry and resistivity toward change in the number of graphene layers.
