In this work. toward an intelligent radio environment for 5G/6G. design methodologies of active split-ring resonators (SRRs) for more efficient dynamic control of metasurfaces are investigated. The relationship between the excitation of circulating-current eigenmode and the asymmetric structure of SRRs is numerically analyzed. https://www.alarecre.com/Wizarding-World-Harry-Potter-Scar-and-Glasses-iPhone-13-Pro-MagSafe-Case-p90262/
