摘要：
Graphene has demonstrated significant advantages in the field of sensing due to its unique electrical and optical properties in the THz regime. Graphene sheets can support surface plasmon polaritons (SPPs) under specific conditions. In the present analytical and numerical study, we analyzed the tunability of the plasmonic sensor based on the surface conductivity of graphene. The analysis has been done with TM polarized waves. The performance parameters of the plasmonic sensor, such as sensitivity, are also tuned and calculated in the present study.
