This paper analyzes the light-scattering properties of the widely-used nanometer or micrometer absorbing magnetic particles at radar wave band based on Mie scattering theory.the effects of the permeability,refractive index and particle sizes on the scattering characteristics are analyzed.The scattering characteristics including scattering intensity,absorption coefficient,scattering coefficient and etc.by magnetic and non-magnetic particles are also compared analytically as well as those by absorbent and transparent particles.Numerical results indicate that the permeability variation has influences on the scattering characteristics such as scattering intensity and absorption property.It is found that the absorption ability increases and back scattering characteristic decreases towards high permeability while its effect on the particles scattering characteristics is restricted simultaneously by the complex refractive index.
