Paper Abstract
We present the first experimental realization of an isotropic IR metamaterial using fourfold-symmetric 3D configuration of metallic nanostructures. Mass-productive formation of the assembled 3D stereostructures was achieved by a newly-developed metal-stress driven self-folding method. Systematic transmission spectroscopy demonstrated unambiguous isotropic characteristics for any lateral rotation, polarization, and incident angle up to 40º. The corresponding numerical simulations well re-produced the experimental results, revealing that the interplay of electric and magnetic interactions of the 3D metallic nanostructures plays a crucial role for the bi-anisotropic responses. Our results demonstrated a promising method to manufacture highly symmetric metamaterials, leading to isotropic optical responses.
