Rigid metamaterials were prepared by embedding TiO2 microspheres into polyethylene. These structures exhibit a series of Mie resonances where the lowest one is associated with a strong dispersion in the effective permeability. Using THz spectroscopy, we confirmed the magnetic nature of the observed resonance.
