A uniaxial‐isotropic IR metamaterial consisting of fourfold‐symmetric 3D split‐ring resonators (SRRs) formed by a metal stress‐driven self‐folding method is fabricated and characterized. Unambiguous isotropic characteristics are demonstrated for any lateral rotation, polarization, and incident angle up to 40°. The corresponding numerical simulations reveal that the interplay of electric and magnetic interactions of the 3D SRR plays a crucial role in the bi‐anisotropic responses.
