In the current study, the refractive index sensor based on Plasmonic Induced Transparency which is composed of graphene meta-material has been investigated. In this sensor one graphene flat layer has been employed it is worth mentioning that two rods have come out of it Plasmonic Induced Transparency was examined by means of symmetry failure. In addition, through using an important feature of graphene in controlled electrical conductivity by changing the voltage range of the frequency range, the Plasmonic Induced Transparency is controlled, besides light slowing was increased to 690. Its sensitivity is 14.88 um/RIU. The structural shape value is calculated as 48. This nanostructure, in addition to its bio-sensing capabilities, can be used for light slowing, optical switches, modulators.Keywords: Biosensor, graphene, light slowing, controllability, Plasmon induced transparency. تفاصيل المقالة
