▎ 摘　　要

Graphene nanoribbon transmission line (GNRTL) is considered as one of the most valuable structures which has been employed in many terahertz devices. A comprehensive analysis of GNRTL is reported by identification of the characteristic impedance and the propagation constant as secondary parameters of graphene nanoribbons transmission line. The impact of different physical and structural factors on the secondary parameters of GNRTL is discussed. Both characteristic impedance and propagation constant are analyzed to obtain an RLC equivalent circuit model which provides valuable insight into the design of terahertz component.
