Co-polarized and cross-polarized electromagnetic scattering of a metallic sphere coated with chiral metamaterials (CMMs) are simulated with Mie series solution. Firstly, based on Bohren's decomposition technique, electromagnetic fields inside and outside of the sphere are expanded in spherical harmonics vector function. Then, the expanded coefficients are obtained in a suitable form for computation by applying the boundary conditions on the interfaces of all regions. The validity of Mie series solution is shown by computing backward scattering for a ferrite-coated metallic sphere. The effects to bistatic, forward and backward scattering caused by incident wave frequency, media parameters of a metallic sphere coated with CMMs are investigated in det
