WebApr 12, 2024 · The RIS, also called the intelligent reflecting surface (IRS), is composed of a large number of passive elements that can reflect the wireless signal independently in the desired direction. When the channel link of the base station (BS) and user equipment (UE) is blocked, the SE improvement is significant in RIS-based wireless communication. WebMultiple reflections: Multiple reflections are the multiple reflections of light back and forth between reflecting surfaces. Multiple reflections occur when a reflected light ray is reflected again after being incident on another surface. Kaleidoscopes and periscopes make use of multiple reflections.
