- To address the issue of beam collapse resulting from instantaneous instability during switch transitions in beam tracking, this paper proposes a novel beam switching method based on a row-by-row switching code table. The paper first establishes an abstract model of the beam tracking application scenario and introduces the reconfigurable intelligent surface (RIS) employed in this paper. Subsequently, simulations are conducted to compare the conventional direct beam switching method with the proposed row-by-row switching code table approach, thereby elucidating the advantages and limitations of the new method. In parallel, a RIS hardware platform is constructed in a microwave anechoic chamber for experimental validation. Both simulation and experimental results show that, by incorporating intermediate state transitions, the approach achieves beam tracking without beam collapse while incurring no significant gain loss. Finally, the paper discusses the applicability scope and potential scenarios for the proposed method. This research provides valuable insights for applications in mobile communications and radar detection.
