摘要：

In this article, the Minkowski shaped tunable metamaterial absorber (MMA) is proposed in near-infrared wavelength and it is varied between 1200 nm and 1600 nm. The tunable absorber shows 99% of the absorption response and its bandwidth can also be varied by different chemical potential of the graphene sheet, which can be controlled by external biasing voltage. In addition, the various physical parameters of the MMA such as silica substrate height, multiple graphene silica layer, and resonator height are numerically investigated. The RLC equivalent circuit model is also observed to study the resonance behaviour over the given wavelength range. The tunable behaviour of the proposed structure paves the way for various fields of biosensor, solar absorption, and optical communication.
