    "abstract": "Expressions arising from the Bruggeman approach for the homogenization of\ndielectric-magnetic composite materials, without ignoring the sizes of the\nspherical particles, are presented. These expressions exhibit the proper limit\nbehavior. The incorporation of size dependence is directly responsible for the\nemergence of dielectric-magnetic coupling in the estimated relative\npermittivity and permeability of the homogenized composite material.",
