Abstract

Structure and composition of metamaterial samples are studied on the basis of lattice packing SiO₂ nanospheres (opal matrices) with included clusters of crystalline phase in interspherical nanospacing related to electrically active or with high inductivity. Real and imaginary components of inductivity of synthesized metamaterials are investigated in range 1 MHz - 2 THz.
