In this work, a novel time domain Transmission Line Matrix (TLM) algorithm with Symmetrical Condensed Node (SCN) is developed to model electromagnetic (EM) wave propagation through a single graphene layer in Terahertz (THz) spectrum. The intraband conductivity of graphene (assumed to follow the Drude model) is implemented in TLM method by using the Auxiliary Differential Equation (ADE) of conduction current density. The validity and stability of the obtained results demonstrate the effectiveness and precision of this new modeling technique named ADE-(SCN)TLM, and prove that this method is a powerful tool that can be used to model and simulate complex devices based on graphene sheet for terahertz applications (e.g., Electronics, optoelectronic, etc.)
