Abstract: A passive Reconfigurable Intelligent Surface (RIS) (102) system (100) for wireless communication employing a ground-splitting architecture to achieve open-loop beam sweeping without conventional electronic tuning components. The RIS (102) comprises of an array of reflective unit cells (104) with a ground plane divided into multiple electrically isolated ground segments (106) coupled to a control signal generator (108). External control signals at distinct frequencies are applied to the ground segments (106), producing phase variations across the surface that dynamically steer reflected electromagnetic waves toward multiple receivers in a sequential manner. The system (100) provides tunable beam sweeping rate, adjustable angular coverage range up to 120 degrees or more, and controllable reflection amplitude. By eliminating RF switches, PIN diodes, and varactor diodes, the invention reduces complexity, lowers cost, improves reliability, and minimizes power consumption. The design is particularly suited for Industrial Internet of Things (IIoT) networks requiring adaptive wireless coverage. (Figure 1)
