Description
Summary:The integration of reflective intelligent surfaces (RISs) with communication systems operating in the Terahertz (THz) range, spanning from 0.1 THz to 10 THz, is recognized as a pivotal technology for the future sixth-generation of wireless communications. A RIS consists of a surface that comprise multiple passive elements that can be engineered to induce phase shifts, enabling the partial control of the incident wave scattering. This unique property holds great potential for mitigating path losses inherent in the THz range, thereby enhancing system coverage. To assess the performance enhancements offered by multiple RISs in a indoor communications system operating at 0.2 THz, this study presents an analysis of the coverage probability in this environment. The simulation results demonstrate that deploying multiple RISs can enhance system coverage by up to 52% and concurrently improve the signal-to-noise ratio by up to 42.5 dB.
