When an applied magnetic field has an arbitrary direction with respect to the lattice axes of a periodically microstructured or nanostructured metamaterial, the effective permittivity tensor of the metamaterial sample becomes anisotropic and all its components can be nonzero. This is true even if the microstructure has a high symmetry, e.g., cubic or triangular. It is found that the strong magneto-induced anisotropy which appears in the macroscopic response leads to unusual anisotropic behavior of the Voigt effect and other magneto-optical (MO) effects. I.e., these phenomena become strongly dependent on the direction of the applied static magnetic field, as well as on the direction of the time dependent electromagnetic field, with respect to the symmetry axes of the periodic microstructure.
