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://safeersappliancers.shop/product-category/bosch-serie-8-hbg674bs1b-integrated-electric-oven-stainless-steel/
