This article presents a pioneering solution to address the challenges of reconfigurable intelligent surface (RIS), employing a cascaded channel decoupling strategy. This novel method streamlines the RIS regulation matrix by dividing the process of electromagnetic wave modulation into two separate sub-processes: virtual receiving response and virtual regular transmission, resulting in the decoupling of the RIS cascaded channel. Furthermore, the paper explores the practical implementation of this channel decoupling method in two typical scenarios, including single-user and multi-user access, offering detailed insights into its application. Through numerical simulations, the article demonstrates the effectiveness and reduced complexity of the proposed scheme in enhancing the efficiency of the RIS regulation matrix.
