N2 - Terahertz (THz) communication is considered to be a pivotal technology in new-generation communication networks. Due to its nature, THz waves attenuate significantly. A blockage will result in a significant power loss, therefore a line-of-sight (LOS) is required. Reconfigurable intelligent surface (RIS) technology is considered to be a promising solution to this problem. In literature, analyses are being done assuming that RIS having lossless reflections and continues phase shifts. In reality, surface reflections differ with the frequency of the incident wave and can have certain phase shifts. Moreover, the design tradeoff between the phase shift range and reflection amplitude should be considered. In this study, a graphene-based RIS has been designed and the communication performance is analyzed using its reflection coefficients and discrete phase shifts.
