Graphene based Ris for thz Wireless Communication

Recent research endeavors have been dedicated to innovative wireless hardware designs and connection concepts aimed at fulfilling the ambitious objectives of 6th Generation (6G) wireless communications. The inclusion of Terahertz (THz) technology in modern infrastructure holds immense potential for shaping 6G networks, offering amplified throughput, extended coverage, heightened security, and improved positioning while reducing power consumption. The demand for efficient control over THz waves has grown alongside the advancements in wireless domain. Reconfigurable Intelligent Surfaces (RIS) have garnered a lot of attention as a means of regulating electromagnetic waves. In this study, we investigate the utilization of a RIS employing graphene-based materials to control THz waves, with a specific focus on enhancing reflection performance and enabling beam steering. Our proposed RIS design entails a periodic array of graphene stacked over a grounded substrate.
