Popis: We report that Babinet complementary patterns of metamaterials (MMs) do not exhibit the same frequency tuning range when integrated with nematic liquid crystals (NLCs). The results of our numerical and experimental studies suggest that this behaviour is controlled by two competing factors: (i) mismatch between the anisotropies of NLCs and local optical fields induced in MMs, (ii) strong orientational nonlinearity of NLCs.
