Size-dependent Bruggeman approach for dielectricmagnetic composite materials
Expressions arising from the Bruggeman approach for the homogenization of dielectricmagnetic composite materials, without ignoring the sizes of the spherical particles, are presented. These expressions exhibit the proper limit behavior. The incorporation of size dependence is directly responsible for the emergence of dielectricmagnetic coupling in the estimated relative permittivity and permeability of the homogenized composite material.
