Mathematical formulation of surface conductivity for graphene material

The graphene material is currently being used in the design of nano components and devices for wireless applications in terahertz (THz) regime as it possesses a number of desirable electromagnetic and mechanical properties that assist in providing flexible and reconfigurable structures. The material tunable conductivity accounts for the superior electromagnetic properties. Very little efforts however are being done to provide simplified solution of the graphene surface conductivity to be utilized for design of nano devices. Hence the authors have presented the simplified analytical solution for graphene surface conductivity expressed in terms of the chemical potential
