Using Maxwell equations, we expand electromagnetic field components in spherical coordinate frame by using spherical vector wave function. According to the constitute relations of the topological insulator (TI), we modify transmittance fields and scattering fields. Using boundary conditions of topological insulator, we obtain the scattering electromagnetic fields. Numerical result show that when the time reversal symmetry is broken, the scattering cross sections are influenced by the topological magneto-electric polarizability.
