Optical magnetism in stratified metal–dielectric metamaterials (SMDM) has been explored numerically. Effective permeability and permittivity in the semi‐infinite SMDM have been extracted by two‐complex reflectivity method. Huge negative permeability has been achieved and found that the real part reaches about –200 at 1.585 eV. The origin of the huge optical magnetism is ascribed to the exotic magnetic field distributions in SMDM. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
