    An all-in-one design is presented for a polarization-insensitive metasurface with a centrally symmetric split-ring structure for generating various resonant modes. The types of resonant modes (LC, dipole, and higher order resonances) are identified and analyzed by investigating their spectroscopic properties theoretically and experimentally. Several higher-order resonant modes have significantly higher quality factors, Q (~230). These resonant modes are also highly sensitive to the dielectric properties of the surrounding material of the metasurface.Additionally, the EM properties of metasurfaces with asymmetric structures were also investigated. It was found that additional resonant modes at both 0.332 and 0.210THz could be excited and strengthened by increasing the asymmetry of the metasurface structure along the horizontal (x-axis) and vertical axes (y-axis).
