Graphene can be utilized as a tunable material for a wide range of infrared wavelength regions due to its tunable conductivity property. In this paper, we use Y-shaped silver material resonator placed over the top of multiple graphene silica-layered structures to realize the perfect absorption over the infrared wavelength region. We propose four different designs by placing the graphene sheet over silica. The absorption and reflectance performance of the structures have been explored for 1500- to 1600-nm wavelength range. The proposed design also explores the absorption tunability of the structure for the different values of graphene chemical potential. We have reported the negative impedance for the perfect absorption for proposed metamaterial absorber structures. All the metamaterial absorbers have reported 99% of its absorption peaks in the infrared wavelength region. These designs can be used as a tunable absorber for narrowband and wideband applications. The proposed designs will become the basic building block of large photonics design which will be applicable for polariser, sensor, and solar applications.

石墨烯由于其可调节的导电性而可用作广泛的红外波长区域的可调节材料。在本文中，我们使用Y形银材料谐振器放置在多个石墨烯二氧化硅层状结构的顶部，以实现在红外波长区域的完美吸收。通过将石墨烯片放在二氧化硅上，我们提出了四种不同的设计。已经研究了该结构在1500至1600 nm波长范围内的吸收和反射性能。拟议的设计还探讨了石墨烯化学势不同时该结构的吸收可调性。我们已经报告了建议的超材料吸收器结构的理想吸收的负阻抗。所有超材料吸收剂都报告了其在红外波长范围内的吸收峰的99％。这些设计可用作窄带和宽带应用的可调吸收器。拟议的设计将成为大型光子学设计的基本组成部分，将适用于偏振器，传感器和太阳能应用。
