    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.
