  Abstract

A reconfigurable intelligent surface (RIS) that artificially reconstructs the wireless environment to achieve high spectral efficiency has been proposed in 5G and 6G broadband communication systems. However, there is no device technology capable of ideal 100% beam tuning, and most studies using integrated circuit (IC)-based metasurfaces have some limitations. This paper first formalizes the relationship in which the additional angular change of the reflected wave is determined by the phase tuning range of the RIS. Next, a methodology for designing RIS through meta-devices such as liquid crystals, 2D materials, and active THz materials is investigated. Thereafter, the performance of the RIS via system-level simulation is evaluated through 3D ray tracing that reflects the realistic communication scenario. Finally, we analyze the RIS system design and beamforming throughput performance that incorporates various meta-devices. As a result, this paper provides useful intuition for designing RIS suitable for the performance and application of the goal.
