In this paper, we propose an experimental method to retrieve all of the 16 effective parameters of planar bi-anisotropic metamaterials. The relationship between the scattering matrix and the effective parameters is theoretically proposed and the experimental measurement for the scattering matrix is accom- plished. We also show the validity of our retrieval method using two microstructures: the cross and the “wan” shaped microstructures. Compared with previous proposed experimental retrieval methods, our experimental method is more universal and can be applicable to any planar struc- tures.
